-- Information about the crash:
- What I was doing when the application crashed:

I clicked on the Akregator Icon in the sidebar. This happens always reproducable

If I call Akregator from CLI it crashes also and issues the following message:

QMetaObject::invokeMethod: No such method KUniqueApplication::loadCommandLineOptionsForNewInstance()
registerWindow Invalid WindowMenu.Registrar! 
KCrash: Application 'akregator' crashing...
<unknown program name>(24381)/: Communication problem with  "akregator" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" " 

KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=/home/hp/.kde/socket-rigel/kdeinit4__0

The crash can be reproduced every time.
