Bug 360220

Application: plasmashell (5.5.5)

Qt Version: 5.5.1
Operating System: Linux 4.4.3-300.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"

-- Information about the crash:
- What I was doing when the application crashed: The screens were in standby(?) mode due to inactivity. I moved the mouse to "wake" them up and this crash happened. I had been running a script to compare files on two different disks and removing equal files from the first disk. The font size on this pop up is TOO SMALL for me to see/read well at all.

- Unusual behavior I noticed Nothing other than these crashes. This is the second crash since I upgraded this system yesterday.:

- Custom settings of the application: I can think of NO settings that might affect this situation.

The crash can be reproduced every time.

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