            Bug ID: 368933
           Summary: Plasma crashed after clicking system tray icon
           Product: plasmashell
           Version: 5.6.5
          Platform: Ubuntu Packages
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: k...@davidedmundson.co.uk
          Reporter: frap...@gmail.com
                CC: bhus...@gmail.com, plasma-b...@kde.org

Application: plasmashell (5.6.5)

Qt Version: 5.5.1
Frameworks Version: 5.23.0
Operating System: Linux 4.4.0-36-generic x86_64
Distribution: Ubuntu 16.04.1 LTS

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

After configuring the entries to show in the system tray, I saved the settings.
Afterwards, I clicked in the icon for themounted devices, and Plasma crashed
and restarted.

Could not reproduce it and settings were saved fine.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
