STEPS TO REPRODUCE 1. Make sure powerdevil is not running, like after a crash 2. run in konsole 'kstart5 /usr/lib/org_kde_powerdevil' OBSERVED RESULT Kstart5 crashes Starting powerdevil without kstart5 works. Is powerdevil supposed to start like this - with kstart5? This bug might be caused by powerdevil and not by kstart5 EXPECTED RESULT Kstart5 starts powerdevil SOFTWARE VERSIONS (available in About System) KDE Plasma Version: 5.14.2 KDE Frameworks Version: 5.51 Qt Version: 5.12-beta3 ADDITIONAL INFORMATION Wayland Log: (altough there isn't much to see) Application: KStart (kstart5), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".

Doesn't crash here, but running this application manually isn't a workflow we support, that's why it's in libexec and not /usr/bin, after all.

I know people normally dont start powerdevil manually, I tried it only because powerdevil crashed so I wanted to start it somehow and then I noticed this.
