            Bug ID: 400633
           Summary: Kstart crashes trying to start powerdevil
           Product: kstart
           Version: 5.14.2
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Severity: normal
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: jari_45 at hotmail.com
  Target Milestone: ---

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
