Application: knotify4 (4.0)
KDE Platform Version: 4.8.4 (4.8.4) (Compiled from sources)
Qt Version: 4.8.1
Operating System: Linux 3.2.0-26-generic x86_64
Distribution: Ubuntu 12.04 LTS

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

It a shame. simple action crash the KDE system. 

Why don't take care, that KDE don't interfere harmfuilly, at least. 

Running some KDE progs, as digiKam 4.6 when starting bleachbit, additionally. 

Why do certain mistakes come back in new versions? 
Does take KDE take care of a stringent quality system at all?

Hope they might learn...

The crash can be reproduced some of the time.
