Bug 362547

Application: kdeinit5 ()

Qt Version: 5.4.2
Operating System: Linux 4.2.0-30-generic i686
Distribution: Ubuntu 16.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I entered my password at the login screen and got the error message as kde was loading plasma. On selecting failsafe instead of plasma it just comes back to the login screen.

The crash can be reproduced every time.

-- Backtrace:
Application: KCMInit (kdeinit5), signal: Segmentation fault
