Application: knotify4 (4.0)
KDE Platform Version: 4.8.3 (4.8.3)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-24-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed: logging in, submitting bug reports, etc.

Every time knotify is invoked it dumps core.  I have akonadi disabled from starting, and nepomuk off.  I don't use many KDE components - mainly stock plasmoids and kwin.   Using fglrx as the openGL provider.

The crash can be reproduced every time.

-- Backtrace:
Application: KNotify (knotify4), signal: Segmentation fault
