Application: systemsettings (1.0)
KDE Platform Version: 4.5.95 (4.6 RC2)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
Several KDE applications (gwenview, system settings, acetoneiso, dolphin) are crashing randomly. call stack has alway upnp stuff in it so it is very likely it is caused by upnp actions. in the network there are 1 win7 system and a fritzbox 7270, both are doing upnp messages. cannot determine which one is causing the problems.

will disable all upnp stuff in fritzbox and wait if there are more crashes

The crash can be reproduced some of the time.
