Application: plasmashell (5.2.2)

Qt Version: 5.4.1
Operating System: Linux 3.19.0-14-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
- What I was doing when the application crashed:
After upgrade to Kubuntu 15.04 Beta 2 every login plasma directly crashes.
The restarted plasma than seems stable.

- Unusual behavior I noticed:
My configuration settings were lost afer the upgrade and compying my old khotkeysrc to .kde/share/config does not seem to have any effect. Maybe there are some old plasma 4 settings that crash plasma 5.

- Custom settings of the application:
I have been using a self made widget in one of my panels, that might be a reason for the crash if plasma tries to load it.

The crash can be reproduced every time.

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