            Bug ID: 361637
           Summary: Systemd KCM crashed when clicking right mouse button
           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: aspotashev at gmail.com

Application: kcmshell5 (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.3-300.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
- What I was doing when the application crashed:

1. Type in some text in the filter textedit, so that the majority of systemd
units hide from the list;
2. Click in the empty space in the list widget with right mouse button.

The crash can be reproduced every time.

-- Backtrace:
