Bug ID: 478970
Summary: plasmawindowed 5.91.0 crashed sometimes when closing
Classification: Plasma
Product: plasmashell
Version: 5.91.0
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: generic-crash
Assignee: plasma-b...@kde.org

Valgrind log with plasmawindowed org.kde.plasma.kickoff
SUMMARY
I ran plasmawindowed org.kde.plasma.kickoff in Konsole in Plasma 5.91.0 on
Wayland in Fedora Rawhide based on https://community.kde.org/Plasma/Debugging
plasmawindowed was blank grey. I maximized plasmawindowed. The main part of the
plasmawindowed window showed a bigger version of the icon like ...> shown on
the Plasma splash screen. I clicked on the main part of the plasmawindowed
window. The Application Launcher menu was shown. The crashes I reported at
https://bugs.kde.org/show_bug.cgi?id=478893 with Plasma 5.90.0 didn't happen. I
closed plasmawindowed. plasmawindowed crashed with an error "corrupted size vs.
prev_size while consolidating" in malloc_printerr in frame 5 of the trace.
Core was generated by `plasmawindowed org.kde.plasma.kickoff'.
Program terminated with signal SIGABRT, Aborted.

The trace appeared to indicate memory corruption while the Plasma applet was
being freed. This crash happened 3/5 times I closed plasmawindowed in this way
STEPS TO REPRODUCE
1. Log in to Plasma 5.91.0 on Wayland in Fedora Rawhide updated from koji
2. Start Konsole
3. plasmawindowed org.kde.plasma.kickoff (in Konsole)
4. maximize plasmawindowed
5. click on the main part of the plasmawindowed window
6. close plasmawindowed
7. If the problem didn't happen, repeated 3-6 until it does
OBSERVED RESULT
plasmawindowed 5.91.0 crashed sometimes when closing
EXPECTED RESULT
plasmawindowed 5.91.0 shouldn't have crashed
SOFTWARE/OS VERSIONS

Invalid frees which might've been double frees were shown later in the log
involving PlasmaQuick::AppletQuickItemPrivate::preloadWeight as in frame 9 of
the crash's trace. plasmawindowed didn't crash when I ran it under valgrind,
but such errors might have resulted in the crashes I saw. I'll attach the full
