Bug 485048

Application: plasmashell (5.27.11)

Qt Version: 5.15.12
Frameworks Version: 5.115.0
Operating System: Linux 5.14.21-150500.55.52-default x86_64
Windowing System: X11
Distribution: "openSUSE Leap 15.5"
DrKonqi: 5.27.11 [KCrashBackend]

-- Information about the crash:
After performing the steps in https://bugs.kde.org/show_bug.cgi?id=347772#c75, plasmashell  (in user1's session) crashes with this stacktrace. 

Sorry for missing Qt debug symbols.

This is because the openSUSE's KDE:/Qt5/openSUSE_Leap_15.5  repo now contains Qt5 5.15.13 which is not installable unless one enables and installes from Q6/Plasma6 repos.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
