Application: knotify4 (4.12.0)
KDE Platform Version: 4.12.0
Qt Version: 4.8.5
Operating System: Linux 3.13.0-rc7-v2k14 x86_64
Distribution (Platform): Gentoo Packages

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

I'm using kdeconnect from git (-> http://albertvaka.wordpress.com/2013/08/05/introducing-kde-connect/) together with my android phone.
Now when i get a phone call, kdeconnect normally stops/pauses players like kaffeine(?)/amarok/smplayer, so i can use my phone without being disturbed by audio/video.
Now sometimes this makes knotify crash with the following backtrace.

The crash can be reproduced sometimes.

-- Backtrace:
Application: KNotify (knotify4), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".
