           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: codewing at web.de
  Target Milestone: ---

Application: kcmshell5 (5.9.0)

Qt Version: 5.8.0
Frameworks Version: 5.30.0
Operating System: Linux 4.9.7-1-ARCH x86_64
Distribution (Platform): Archlinux Packages

-- Information about the crash:
- What I was doing when the application crashed:
Disconnected from a network

Everytime I disconnect from a network the connection screen shows all
avalilable connections and each of them multiple times.

The crash can be reproduced sometimes.
