[krita] [Bug 420612] Krita: Segmentation fault when closing
https://bugs.kde.org/show_bug.cgi?id=420612 Tiar changed: What|Removed |Added CC||tamtamy.tym...@gmail.com --- Comment #11 from Tiar --- @kd3 @Lynx3D @kevin Can you please check if e7bd37c699944a fixes the crash on startup for you? I have the same Qt version and I was getting the same backtrace, so I hope it did fix/prevent it. If you don't build your own Krita, please check Krita Next #1228, which should contain this change. You can run it from the terminal or bst, through gdb, to see the crash. -- You are receiving this mail because: You are watching all bug changes.

Committed on 22/04/2021 at 14:13. Pushed by tymond into branch 'master'. Fix crash on exit by setting styleSheet only on QTabBar Before this commit, Krita would crash on exit on Qt 5.12.8 with segfault in the destructor for the Python plugin widgets. It turned out that this crash was introduced in 8a7bae681a1f992, and the reason turned out to be a method setStyleSheet() with non-empty string. Setting empty stylesheet later (on closing) didn't make a difference. However setting the stylesheet on just the widget that needs it (QTabBar that keeps the document tabs) fixes/prevents the crash. Alternative fix would be to find the widget for the Python plugin and explicitely set empty stylesheet after every non-empty stylesheet set for the whole application. It wasn't tested, but in case more widgets need non-empty stylesheet, it sounds like it should work.

https://bugs.kde.org/show_bug.cgi?id=420612 --- Comment #7 from Lynx3d --- For me it is krita built from source with all dependencies from Ubuntu packages. Since using system-wide Qt seems the only practical way to have the Breeze style engine, I don't really know any alternative to test besides Ubuntu packages and compiles that should be equivalent to those. However I just went through all the Python plugins, and the "Comics Project Managment Tools" seems to cause the crash for me, after disabling this plugin I can use the Breeze style without crashes. -- You are receiving this mail because: You are watching all bug changes.

I'm pretty new on linux, I don't want to venture too much in dark places. I get the same error message at closing, segmentation fault.

https://bugs.kde.org/show_bug.cgi?id=420612 --- Comment #3 from Lynx3d --- Should have read the above backtrace more carefully, it always seems to happen when unloading pykrita plugin, the other threads don't matter. And after plenty of tries, it always crashes with the Breeze style here, and never with the Fusion style. Since tiar had a hard time finding a crash that turned out to be caused by incorrectly usage of a style object in KisColorFilterCombo I tested if that fix also works for this crash, but unfortunately not...I don't really have a clue what might be happening here, I couldn't find similar mistakes elsewhere (yet). -- You are receiving this mail because: You are watching all bug changes.

Then I built my own Qt again and no crash. I have a feeling it has to do with the breeze theme, running krita (built with system Qt) with -style=fusion gave me no crash on a few tries, with the default breeze it seems to crash every time, either with this backtrace or when unloading pykrita. -- You are receiving this mail because: You are watching all bug changes.
