Extract of crash from /var/log/messages
SUMMARY
Kwin crashes out of the blue on an unloaded system, seemingly unrelated to
ongoing light user activity.
System had copious free RAM and CPU and is airgapped, so that external causes
can be precluded.
Kwin was quickly restarted by systemd – so usability impact was low …
Backtrace cannot be provided as DrKonqui failed to start (obviously …).
STEPS TO REPRODUCE
1. not known
OBSERVED RESULT
Kwin crashes
EXPECTED RESULT
Kwin shouldn't crash
