            Bug ID: 359433
           Summary: [OS X] systemsettings5/kcmshell5 crash on 2nd attempt
                    to create activity
           Product: systemsettings
           Version: 5.5.4
          Platform: Compiled Sources
                OS: OS X
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: plasma-b...@kde.org
          Reporter: rjvber...@gmail.com

Application: systemsettings5 (5.5.4)
 (Compiled from sources)
Qt Version: 5.5.1
Operating System: Darwin 13.4.0 x86_64
Distribution (Platform): MacPorts Packages

-- Information about the crash:
I'm unsure if this is an actual bug somewhere in KF5 or actually in Qt ... nor
to what extent the "create activity" feature is meaningful on OS X.

- What I was doing when the application crashed:

(see terminal about below)
1a) launch systemsettings5 
2a) open the activities KCM

or

1b) kcmshell5 kcm_activities

3) click "create activity"
4) close the dialog (via cancel or OK, without any modification)
5) repeat 3)

6) crash, DrKonqi is started.

Terminal output:
