KDE Platform Version: 4.8.5 (4.8.5)

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

Every time I resume the desktop from suspend, KNotify crash.

Also, now it crashed when I closed an open window of KWrite before the "do you want to save" had a chance to pop up.

The crash can be reproduced every time.

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