Created attachment 161742 [details] Section of journal log showing restart of plasma and crash/core dump. SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Upgrade from plasma-desktop 5.27.5 to 5.27.8 2. Restart plasma desktop 3. Mouse select program icon in system tray. QT based programs seem the most vulnerable like keepassxc. There is no such problem under plasma-desktop 5.27.5. OBSERVED RESULT plasma-desktop crashes "core-dump" in system log. EXPECTED RESULT Program opens as normal as in 5.27.5 SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Linux 6.5.3-1-MANJARO x86_64 (available in About System) KDE Plasma Version: 5.27.8 KDE Frameworks Version: 5.110.0 Qt Version: 5.15.10 ADDITIONAL INFORMATION
Created attachment 161743 [details] coredumpctl log
Can you please generate a symbolicated backtrace from that stack trace? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl Also, does it happen when you click on *every* system tray icon, or only some. If only some, which ones specifically?
Created attachment 161760 [details] coredumpctl log following guide instructions It seems the trigger to cause the crash was minimizing any open window. It is not related to the system tray other than some applications are minimized there.
I'm afraid the file you attached still has an un-symbolicated stack trace, rather than a symbolicated backtrace. If you need help doing this, I might recommend reaching out to the Debian folks.
Created attachment 161783 [details] Backtrace with debug symbol applications installed I hope this is of some use? It looks like a problem is in /usr/lib/libQt5Core.so.5 or dependencies.
