-- Information about the crash:
After upgrading (using 'preupgrade') Fedora 15 to Fedora 16, all K-games which worked fine in *both* KDE and Gnome, now cause a KNotify crash. My guess is that this is caused by KNotify's inability to play the sounds usually associated with K-games. This assumption is amplified by the fact that when possible (in games such as KNetWalk and KSame), I disabled the sounds, and decreased therewith the KNotify crashes markedly. 
Nevertheless, KNotify crashes at least once per play, i.e. at the end of the game. My sound system seems to be okay; it reproduces e.g. YouTube and DVD movie sounds just as before upgrading.
This bug is really annoying because it appears dozens of times in each gaming session. Is there a way of disabling KNotify altogether? A 'yum remove' would probably erase a lot of packages I want to keep...

The crash can be reproduced every time.
