Application: knotify4 (4.14.2)
KDE Platform Version: 4.14.2
Qt Version: 4.8.7
Operating System: Linux 3.16.0-4-amd64 x86_64
Distribution: Debian GNU/Linux testing (stretch)

-- Information about the crash:
- What I was doing when the application crashed:
With a file selected in the dolphin file browser, I pressed shift+delete to permanently delete it. The KDE Crash Handler immediately popped up saying that KNotify was crashed.
- Custom settings of the application:
the system has no display manager and the window manager is i3 (started by startx)

The crash can be reproduced every time.

-- Backtrace:
Application: KNotify (knotify4), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
