Application: plasmashell (5.5.3)

Qt Version: 5.5.1
Operating System: Linux 4.1.13-5-default x86_64
Distribution (Platform): openSUSE RPMs

-- Information about the crash:
- What I was doing when the application crashed:
I right-clicked a link in Konsole and selected "Open Link". If a Firefox instance on another virtual desktop is open, the link is opened there and Plasma _sometimes_ crashes a few seconds later
- Custom settings of the application:
Four virtual desktops, Konsole and Firefox on different ones

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
