Bug 310289

Application: kded4 ($Id$)
KDE Platform Version: 4.9.80 (Compiled from sources)
Qt Version: 4.8.4
Operating System: Linux 3.6.6-1-ARCH x86_64

-- Information about the crash:
- What I was doing when the application crashed:
I was opening my session, after compiling latest sources with kdesrc-build

- Unusual behavior I noticed:
Plasma shell crashes when notifications it receives notifications from other systems. I figure this crash lets it in an unstable state. Please see the next reports, as three crashes occurs on session start origintaing in kmix.

The crash can be reproduced every time.

-- Backtrace:
Application: KDE Daemon (kdeinit4), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".
