-- Information about the crash:
I have dolphin configured to show delete with confirmation in the RMB menu.

Activating this option on a file using the RMB, the confirmation and delete were successful but knotify launched the crash reporter

The crash can be reproduced every time.

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