Application: org_kde_powerdevil ()

Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 5.0.0-31-generic x86_64
Distribution: Ubuntu 18.04.3 LTS

-- Information about the crash:
There was a power outage. My notebook was running on its battery. The status was odd as first the battery indicator went down properly but later it jumped back to 100%. Possibly an issue with the notebook or its battery, I never had to use it before.

After while I came back when the power was back on. The notebook had gone to "sleep". I resumed it and then was greeted with this crash.

-- Backtrace:
Application: org_kde_powerdevil (org_kde_powerdevil), signal: Segmentation fault
