Description Diederik van der Boor 2008-06-07 13:08:12 UTC 
Version:           onbekend (using 4.00.80 (KDE 4.0.80 >= (KDE 4.1 Beta1) "release 3.2", compiled sources)
Compiler:          gcc
OS:                Linux (i686) release 2.6.22.17-0.1-default

When running KDE4 applications at a KDE 3 desktop, or Windows environment they get completely frozen while knotify starts up. This also happens when the application only needs to display a simple KMessageBox, which looks quite silly.

To fix this bug I think the following is needed:
- avoid blocking the application for simple message boxes. If the messagebox is closed before knotify4 is up, just don't play the sound.
- let applications start knotify4 in the background if they are sure they'll need it at some point.

Have you experienced this bug again with a recent KDE version? (4.1.3 / 4.2beta2 / 4.2svn) ?  Thanks :)

No I haven't seen this issue anymore
