-- Information about the crash:
- What I was doing when the application crashed:
After update finishes, hit 'back' button. It asks for re-sending information. Click apply. Apper tells the related search is invalid and crashes.

The crash can be reproduced every time.

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