Application: plasmashell (5.3.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-lowlatency x86_64
Distribution: Ubuntu 15.04

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

I had left an Alt-F1 terminal showing when I turned of the TV monitor. On switching back to the plasma desktop (Alt-F7) I got the crash report

- Unusual behavior I noticed:

The desktop background and bars were missing, but the windows to running programs were still there.

The crash can be reproduced every time.

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