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.
