Program crash when clicking on "New Project"

This is the output from tMVStudio

The file /usr/share/icons/Adwaita/16x16/status/image-missing.png actually exists and I was able to open it with GIMP.

I built MVStudio from source (git commit 50adf8b8552057104d84e006c02445756ae0ec4b) on Debian 11 (updated today) using cmake, once copilation finished I run "make install" and then ./Release/MVStudio.

This is the list of packages installed on my Debian system: installed_packages.txt

Tried to run MVStudio again and this time got a SegFault when clicking "Open Project"

This is weird: the code never explicitly requires the images/icons. I believe some UI components need them.
The binary was built on Ubuntu (18.04) and I am not sure if it can run on Debian. If you have time, would you be so kind to run it in Debug mode and send me snapshots of the stack trace? I don't have Debian, and it seems this is the only way I can debug it.

[marco-jem]

Yep sure! Not at home right now, will do it tonight.

By the way I get the same error on Ubuntu 20.04.4 LTS using the pre compiled package (AppImage), this is the output

Hi! Tried a new build with flag CMAKE_BUILD_TYPE=Debug, but nothing changes in the output (no stack trace, just the same output as in my first post). Which options am I supposed to pass to cmake to do a debug build?

[LiangliangNan]

Yes, that is correct. Thanks for the effort. The next thing is debugging, letting the debugger (gdb on your machine, I believe) produce the stack trace. I think you can start the debugging by the command gdb MVStudio (or maybe you already have some advanced IDE tools).

Thanks for the effort! This seems like a bug in the QFileDialog of Qt (I assume the file "image-missing.png" is not corrupted). Does any other Qt-based applications (that use the same Qt distribution) have a similar issue? What is your Qt version, and if you can try a later version?

[LiangliangNan]

@marco-jem Has the issue been solved (by using the latest code) and can we close the issue?
