  Yes, for me it happens all the time when I try to adjust screen brightness after switching between VT's.
  
  Here is the error that I get with my patch:
  KAuth::Polkit1Backend::actionStatus: Encountered error while checking action status, error code: 2 "GDBus.Error:org.freedesktop.PolicyKit1.Error.Failed: Action org.kde.powerdevil.discretegpuhelper.hasdualgpu is not registered"
  
  Sure one has to fix this error in the first place, but it's always a good thing to error-proof the code.
