Kontact not starting

I am running KDE4.4.3 with Milestone 6. Whenever I start Kontact, it craches with the following message(s):

Connecting to deprecated signal QDBusConnectionInterface::serviceOwnerChanged(QString,QString,QString)
<unknown program name>(4716)/: Communication problem with “kontact” , it probably crashed.
Error message was: “org.freedesktop.DBus.Error.NoReply” : " “Message did not receive a reply (timeout by message bus)” "

KCrash: Application ‘kontact’ crashing…

Has anyone else seen this error? Does anyone have a suggestion as to how to solve it?

This problem has been fixed. If you haven’t done an update do so to get the fix.
