Description jsmith 2016-02-26 14:18:15 UTC 
Application: plasmashell (5.5.4)

Qt Version: 5.5.1
Operating System: Linux 4.3.4-300.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

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

Running Fedora 23 with Plasma in a VirtualBox hosted on Windows 7. Plasma crashed while I was not actively in the VirtualBox (window had been minimized, when I reopened it, I had the crash wwindow).

This happensto me multiple times a day - not always when VirtualBox is minimized. I cannot link it to any specific user action - sometime just moving the mouse between windows when this occurs.

The crash can be reproduced sometimes.

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