-- Information about the crash:
Here is one backtrace that I could get. Plasma crashed this time while I was trying to activate nepomuk services in the system settings. - It may also be that my WLan connection is now unstable (which it has not been with kde 3.4)

 -- Backtrace:
Application: Plasma-Arbeitsfläche (kdeinit4), signal: Segmentation fault
