Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-15-generic i686
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
I upgraded from Kubuntu 14.10 to 15.04. After boot, nothing is displayed (white screen) except of the mouse cursor. Everything looks to be working except graphics because when i type my password, system logs me in BUT, again, nothing is displayed. After few minutes, lots of crash reports of plasmashell is displayed. Also, i was able to run a console (using the Debug button on the crash report) and in htop i saw about 30 plasmashell running with --shut-up arguemnt and taking 100% CPU.

HW is old ThinkPad R51 with ATI Radeon 7500 graphic card.


- Unusual behavior I noticed:

When i start systemsettings5 (using a console) and try to show desktop effects, it crashes with error something like: QOpenGL.....: cannot open shader (don't remember the exact message).

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/lib/i386-linux-gnu/libthread_db.so.1".
