Sentry Crash Report:

Description Leighton Brown 2015-09-15 12:16:00 UTC 
Application: plasmashell (5.3.2)

Qt Version: 5.5.0
Operating System: Linux 4.1.5-200.fc22.x86_64 x86_64
Distribution: "Fedora release 22 (Twenty Two)"

-- Information about the crash:
- What I was doing when the application crashed:
After upgrading from kf5 5.12 to 5.13 plasma fails to start with a openGL version incompatibility error. Downgrading the 5.9 which worked before does not resolve the problem. Problem occurs now each time plasma should start. (after login). Firefox starts without issue.

The crash can be reproduced every time.

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