Bug 294588

Application: knotify4 (4.0)
KDE Platform Version: 4.4.4 (KDE 4.4.4) "release 3"
Qt Version: 4.6.3
Operating System: Linux 2.6.34-0.1-default i686
Distribution: "openSUSE 11.3 (i586)"

-- Information about the crash:
KNotify popped up for an event: Firefox web browser notified that an update was available.

I clicked the notification popup.  Firefox opened, and the notification popup went away, as expected.

However, a few seconds later, the same notification popup appeared again!

I clicked on this notification popup, with Firefox in the foreground already, and then KNotify crashed with this segfault.


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