Bug 195486

Application that crashed: knotify4
Version of the application: 4.0
KDE Version: 4.2.90 (KDE 4.2.90 (KDE 4.3 Beta2))
Qt Version: 4.5.1
Operating System: Linux 2.6.29-2-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
Fresh install of KDE trunk from today (svn r978265), compiled and installed, and I'm greeted with this crash straight away on logging in. It looks similar to bug #161571 but the assert seems to be in a different place, so I guess its not a simple duplicate.
