Bug ID: 406320
Summary: Powerdevil SEGV in onServiceUnregistered
Product: Powerdevil
Version: 5.15.2
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: ber...@codewiz.org
Target Milestone: ---
SUMMARY
Powerdevil crashes every now and then (it happened 5 or 6 times in two weeks).
It seems to happen around suspend/resume, but I'm not sure.
This time I attached GDB and collected this stack trace, hoping it's enough to
pinpoint the issue:
Thread 1 "org_kde_powerde" received signal SIGSEGV, Segmentation fault.
