Reported first on openSUSE bugzilla: https://bugzilla.opensuse.org/show_bug.cgi?id=1211628 I bring this bug upstream to reach people knowing more on plasma. SUMMARY plasmashell crashes on 1st start on (unreleased) openSUSE Tumbleweed aarch64 with the following trace from coredumpctl gdb. #0 0x0000ffff98f66618 in __pthread_kill_implementation () from /lib64/libc.so.6 #1 0x0000ffff98f1e8c0 in raise () from /lib64/libc.so.6 #2 0x0000ffff9b8e79d8 in KCrash::defaultCrashHandler(int) () from /lib64/libKF5Crash.so.5 #3 <signal handler called> #4 0x0000ffff98f66618 in __pthread_kill_implementation () from /lib64/libc.so.6 #5 0x0000ffff98f1e8c0 in raise () from /lib64/libc.so.6 #6 <signal handler called> #7 0x0000ffff98fc6090 in poll () from /lib64/libc.so.6 #8 0x0000ffff97c125b0 in ??

This started zhen ze updated from 5.27.4 to 5.27.5 and it happens in X11 only. STEPS TO REPRODUCE Install unreleased openSUSE Tumbleweed for aarch64. X11 only. OBSERVED RESULT Theme is not applied properly and we get traces in journal. EXPECTED RESULT Theme should be applied properly and no crash should happen. SOFTWARE/OS VERSIONS Linux/KDE Plasma: openSUSE Tumbleweed (available in About System) KDE Plasma Version: 5.27.5 KDE Frameworks Version: 5.106.0 Qt Version: 5.15.9 ADDITIONAL INFORMATION
Backtrace does not contain any evidence of KDE code. Possibly a Qt issue or a setup/packaging issue. You said you're using "(unreleased) openSUSE Tumbleweed aarch64"; can you describe the hardware and software setup a bit more?

The screenshot showing the issue can be seen here: https://openqa.opensuse.org/tests/3337754#step/opensuse_welcome/4 and can be compared to https://openqa.opensuse.org/tests/3279201#step/opensuse_welcome/4 I wrote unreleased, because QA is blocking the updates delivered to users due to this bug.

Any ideas, Fabian?
So, this is this Qt issue: https://bugreports.qt.io/browse/QTBUG-111935 And the (tested) fix is: https://code.qt.io/cgit/qt/qtdeclarative.git/commit/?id=15ec024152a1d1d99a4934f7b2408e7af7b2552a Which should have been pushed to 5.15 branch, but is not in yet apparently.
Thanks for following up!
