Bug 224483

Application: plasma-desktop (0.3)
KDE Platform Version: 4.3.95 (KDE 4.3.95 (KDE 4.4 RC2))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-18-generic i686
Distribution: Ubuntu 9.10

-- 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
