Menu and other icons missing (as root & user) - Debian 13 with Gnome DE
Describe the problem, feature or ask a question:
Hi All,
Firstly apologies if I do something wrong with this report, I've never used github or reported a bug before!
I've tried installing backintime on two different Debian 13 machines using the Gnome DE and have the same issue. Most of the icons are missing, both the menu icons and in the snapshot view (folder icons) This occurs when running Back in Time (root) and Back in Time as standard user. Screenshot below:
Back in time was installed from the Debian repository. I've tried both from Gnome software store, as well as command line... installing both backintime-common and backintime-qt. All have same result. I recently migrated from Linux Mint Cinnamon and backintime worked fine there, so seems to be unique to the Debian/Gnome setup?
I found this issue which appears very similar to mine: https://github.com/bit-team/backintime/issues/1836 I did note however that issue appears to only affect when running as root user. My issue occurs both as root and standard user.
Debug output:

Hello gamerdad,
Thank you for taking the time to report the bug and providing the details. I appreciate your feedback, will investigate the issue, and work on a solution to the best of my ability.
Firstly apologies if I do something wrong with this report, I've never used github or reported a bug before!
You are doing well. It is a fine report. No need to apologize.
I am still puzzled with this issue because it seems I don't understand all technical details. That is why I have not real solution.
Might it be that you are using qt6ct? This is a tool influence the visual appearance of Qt applications. But I am not sure how it fits into the big picture here. It is just a guess.
Can you please show me the output of ls -l /usr/share/icons and ls -l /usr/share/icons/hicolor?
I am also interested in the output of apt-cache policy hicolor-icon-theme.
If you have any more details to share, feel free to reach out.
Not sure when we'll find the time to work on it. Please see the projects background information to get an idea about our workflow and priorities:
Best regards, Christian

Thanks for your time to look into this and get back to me, I appreciate it!
Might it be that you are using qt6ct? This is a tool influence the visual appearance of Qt applications. But I am not sure how it fits into the big picture here. It is just a guess.
Sorry, I'm not sure.... how would I check? I was using Google Gemini (I know) to try and diagnose the problem of missing icons and I think it suggested I install that qt6ct application to change QT theming options. I wasn't really sure how to use it and get an error on opening the qt6ct application anyway, maybe that helps pinpoint the issue perhaps?
After all that mucking around, I installed back in time on my laptop which has a fresh Debian 13 with Gnome install. Same issue with missing icons on that machine as well.... so I don't think I broke anything with my tinkering earlier on first machine :)
Can you please show me the output of ls -l /usr/share/icons and ls -l /usr/share/icons/hicolor?

Just to follow on from my previous post, I just spun up a new VM of Debian 13 with Gnome. I wanted a completely fresh install to rule out any issues brought on from my own earlier troubleshooting on my main workstation.
Brand new Debian 13 with Gnome install. Only thing I've done on this machine is Apt update and upgrade, install backintime-qt from repository. Getting same issue with missing icons:

Hello, thanks for the diagnosis data.
I never used qt6ct myself. In my understanding it somehow overwrites the desktop environments theme settings regarding Qt applications. It somehow interfere with the "usual way". That application is not a solution. Just uninstall it. You won't need it.
Fresh Debian 13 with Gnome. Nice to know. Did you used the netinstall ISO image? In the installer you selected this components?
I will check in a VM, too.
Regards, Christian

Thanks, will uninstall it.
Fresh Debian 13 with Gnome. Nice to know. Did you used the netinstall ISO image? In the installer you selected this components?
Yes I used the netinst ISO (debian-13.1.0-amd64-netinst.iso). And those are the options I selected during install, they were the default options in the installer.
Thanks for your help!
So I've done a bit more fiddling and managed to get the icons working as standard user. I had to install the package adwaita-icon-theme-legacy. Appears that package not installed by default on Debian 13. Now the icons appear correctly:
However if I launch Back in Time (root) from the Gnome application menu, the icons still don't work:
But if I launch from terminal via "sudo backintime-qt", the Icons do work:
I'm not sure if there are any implications in running via "sudo backintime-qt" as opposed to the application launcher shortcut? I like to use back in time as root, as I use it to back up multiple users home directories automatically every system boot.
Anyways hope this info may provide useful :)
Thank you for further testing. I really appreciate that.
To start BIT in root mode just use backintime-qt_polkit.
There is a pending pull request #2291 I need to check first. It might solve the problem.
What still gets me puzzled why BIT is not able to use the hicolor theme.
I will dive into it when I have some more time.
