Bug 337569

Application: kded5 ()

Qt Version: 5.3.1
Operating System: Linux 3.13.0-32-generic x86_64
Distribution: Ubuntu 14.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I had just unlocked the computer after resume from suspend.

- Unusual behavior I noticed:
When I was typing the password to unlock the text field lost focus ind the middle. Principially I might have hit the touchpad, but I don't think so.

-- Backtrace:
Application: kded5 (kded5), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
