--- Comment #4 from Hadrien G. <knights_of...@gmx.com> --- Most of the coredumps are from plasmashell from resuming from sleep or power-cycling the monitor, which I suspect to be a different issue. I should probably create a different bug report for those crashes. But if you prefer, I can add some of them here. However, there are actually a few that I missed from kscreenlocker_greet. Here is the most recent one: Core was generated by `/usr/lib/kscreenlocker_greet --testing'.

What I did not manage to figure out so far is, who overwrote that memory and why. It would have been great if the crash reproduced under rr or valgrind... -- You are receiving this mail because: You are watching all bug changes.
