Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-18-generic x86_64
Distribution: Ubuntu 15.04

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

The crash appeared when I did a right click on Kleopatras Tray Icon and clicked on Shutdown Kleopatra and after some other clicks on tray icons.
This is a dublicate of #343971 but I can't mark it as dublicate as the bug reporter failed...

- Unusual behavior I noticed:

Kleopatra didn't really react on my clicks.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
