Bug 248238

Application: knotify4 (4.0)
KDE Platform Version: 4.5.00 (KDE 4.5.0)
Qt Version: 4.6.3
Operating System: Linux 2.6.31.12-0.2-desktop x86_64
Distribution: "openSUSE 11.2 (x86_64)"

-- Information about the crash:
KNotify random crashes when reporting Phonon configuration problems (which happens every time at login for me, probably while waiting for devices to appear) and KMail incoming e-mails.

The crash can be reproduced some of the time.

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