Git commit e7bd37c699944a78cde620b52118d254a254b708 by Agata Cacko. 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.

I have the same Qt version and I was getting the same backtrace, so I hope it did fix/prevent it. |
Created attachment 132018 [details] Krita crash stacktrace SUMMARY Krita often crashes on normal close after saving files. This is not a major issue because all files save OK. No real data is lost but closing the application normally should not create a crash. STEPS TO REPRODUCE 1. Work on Krita with some painting for some time 2. Save the file 3. Close Krita OBSERVED RESULT On close kcrash reports that Krita closed unexpectedly. EXPECTED RESULT Krita should close normally SOFTWARE/OS VERSIONS Operating System: Kubuntu 20.04 KDE Plasma Version: 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 Kernel Version: 5.4.0-48-generic OS Type: 64-bit Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz Memory: 7.6 GiB of RAM ADDITIONAL INFORMATION I have attached the a stack trace.
