Application: knotify4 (4.0)
KDE Platform Version: 4.6.40 (4.7 >= 20101222) (Compiled from sources)
Qt Version: 4.7.1
Operating System: Linux 2.6.36-ARCH i686

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

Solid keeps randomly crashing. Mostly it crashes when I click on a link in Konversation which opens up a new tab in chromium.

This has nothing to do with external storage devices. I have 2 hard disks and those are always mounted.

Btw, plasma also crashes along with KNotify ( and sometimes dolphin ) Exact same backtrace.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KNotify (knotify4), signal: Aborted
