Bug 307091

Application: knotify4 (4.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.2.0-3-686-pae i686
Distribution: Debian GNU/Linux testing (wheezy)

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

I installed Debian Wheezy (the version that is supposed to become the next stable Debian for a couple of years...) and logged into KDE. Boom. Crash. Got this backtrace. This doesn't look too good...

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