KDE-3.4.0 and knotes / kontact problem

[Sascha Brechenmacher <sb@q-leap.de>]

Hello,

I have a peoblem after the update of KDE-3.3 to KDE-3.4 with my kontact and 
knotes application. After I try to open knotes in kontact I receive:

kontact: WARNING: Cannot execute call to system.login: empty server URL

and kontact is freezed.

If I try to open knotes from the shell i receive a:

knotes: WARNING: Cannot execute call to system.login: empty server URL

and the knotes process is freezed. 
With KDE-3.3 knotes and kontact works fine. Hope somebody could help me.

Regards,
Sascha
