    <thetext>Application: plasmashell (5.3.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-30-lowlatency x86_64
Distribution: Ubuntu 15.04

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

Restarting with an updated kernel.

- Unusual behavior I noticed:

A complelely black screen.Alt-F1 got me a terminal. startx brought up two windows and plasmashell crash reports

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library &quot;/lib/x86_64-linux-gnu/libthread_db.so.1&quot;.
