Qt Version: 5.4.1
Operating System: Linux 3.19.0-26-generic x86_64
Distribution: Ubuntu 15.04

-- Information about the crash:
I am sure there are plenty of duplicates out there for this bug, but when I select one in Dr. Korgi, it never stays selected so I have to type something in here. Another bug perhaps? Sorry.

The crash can be reproduced every time.
