Crash log for all threads
SUMMARY
It happens randomly, I don't see anything specific in the crash log.
Possibly I caused it myself by 148a5e9bb784d4d84ff5595 (both cases when it
happened it was with that changes) but I don't see how it could be relevant...
STEPS TO REPRODUCE
1. Start Krita.
2. Possibly press some buttons (I think I was typing at the moment, both times
it happened I was doing something)
3. Krita steals the focus and crashes.
OBSERVED RESULT
Segfault/crash
EXPECTED RESULT
No crash
