If this not enough information for debug, please tell me. I'll ask original reported or send you all attachments since bug is private.

I’ll try something simple, but I’m guessing that I will need to know the sequence of changes to determine the cause of the segfault. All I know from this report is that the user clicked on the undo button which undid a node attachment. I’ll look into this problem this evening.

[phase1geo]

Yes, I am unable to reproduce this issue. I'm going to some extra instruction in how to reproduce this problem.

[tim77]

Waiting for OP. Probably safe to make bug public, but let's wait for OP a little bit.

[phase1geo]

Is there anything happening with this issue still? I'd like to get this issue resolved, if possible, very soon as I'm looking to get a new stable release made within the next couple of days.

[tim77]

Readdressed and now you can see original bug report https://bugzilla.redhat.com/show_bug.cgi?id=1845485#c13

I think I am getting the same error on arch linux with ver 1.10.0 and 1.11.0. Ver 1.9.0 is working fine. I dont know how to submit bugreport, but when I run minder from terminal it gives Segmentation fault (core dumped) error. On using strace it gives

--- SIGSEGV {si_signo=SIGSEGV, si_code=SEGV_MAPERR, si_addr=NULL} ---
+++ killed by SIGSEGV (core dumped) +++
Segmentation fault (core dumped)

EDIT: I am using Arch Linux and tried building it using makepkg and again without makepkg but both give same output.

[phase1geo]

@Lokawn Does version 1.11.1 address this problem? If not, it would be good to run Minder under gdb so that we can get a stacktrace of the crash.

[Lokawn]

Same error in ver 1.11.1 backtrace.log

EDIT: Read ArchWiki for preparing stacktrace and uploaded new stacktrace.

[phase1geo]

I have checked in some changes to the master branch to help deal with this issue. Is there any way that you can try grabbing the GitHub source code and running from that to see if the issue still persists?

[Lokawn]

still getting same error. new_trace.log

[phase1geo]

I have updated the master branch once more in another attempt to circumvent a segmentation fault on launch. Please give this another try. If this doesn't work either, you will need to delete ~/.local/share/minder/custom_themes.xml and relaunch Minder. This will effectively remove any custom themes that you have previously created and keep the application from crashing on startup.

I would appreciate it if you could try the latest master branch change prior to removing the themes file and let me know the result.

[Lokawn]

Build with new sources - App Didn't work. trace1.log

Remove ~/.local/share/minder/custom_themes.xml & ~/.local/share/minder/tab_state.xml (files listed here used the custom theme) & then start - App is Working. custom_themes.xml

Going to try this with ver 1.11.1. EDIT: Same thing happens in ver 1.11.1, looks like I wasted your time for nothing.

[phase1geo]

@Lokawn The error reported above is different from the problem listed above. Could you try running the latest master branch code by downloading it from GitHub and running './app debug' to run the application under gdb. I'm interested in the stack trace when the application crashes in your case.

[Lokawn]

Restored original custom_theme.xml, then executed ./app debug stacktrace.txt
