Application: plasmashell (5.3.0)

Qt Version: 5.4.1
Operating System: Linux 3.19.5-200.fc21.x86_64 x86_64
Distribution (Platform): Fedora RPMs

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

I was trying to switch "Application Launcher" to "Application Menu" through "Alternatives". Also I tried to add this launcher by "Add Widgets...". After that crash appears.

I use Fedora 21 with dvratil copr. Problem appeared after fresh update to plasma 5.3.

The crash can be reproduced every time.

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