           Version: 5.11.0
          Platform: Other
                OS: Linux

          Severity: normal
          Priority: NOR
         Component: general
          Assignee: plasma-b...@kde.org
          Reporter: tho...@mitterfellner.at
  Target Milestone: ---

The new Systemsettings dialog crashes when I do this:

2) Quickly type "cla" on the Keyboard 

Slowly typing c, l, a does not crash the program.
