Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.6-300.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
- What I was doing when the application crashed: I have had several days with NO crashes like this one. I've been cheering all those who put in the massive amount of time to fix the problem. I was navigating from desktop #1 to #2 via the button for virtualbox in the task bar when this crash happened. Maybe it's the same one "we've" been chasing for some time or maybe not.

The crash can be reproduced sometimes.

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