Bug 358035

Application: knotify4 (4.14.9)
KDE Platform Version: 4.14.9
Qt Version: 4.8.6
Operating System: Linux 3.16.7-29-desktop x86_64
Distribution: "openSUSE 13.2 (Harlequin) (x86_64)"

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

I had just clicked on the online update icon and agreed to update when the notification box for package dependency failure popped up and I got notified of a KNotify crash.

Note: Knotify has crashed at least 4 more times in the course of reporting.

-- Backtrace:
Application: KNotify (knotify4), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
