Version:           1.5.2 (using KDE 4.6.3) 
OS:                Linux

I am using Kontact with a KOlab account. After I have configured the addressbook as described in the KDE userbase, Kontact often crashes. After the crash I cannot restart it because it cannot connect to akondi through dbus.


Reproducible: Sometimes

Steps to Reproduce:
Configure Kontact with the kolabwizard, then configure the address book as described in http://userbase.kde.org/KAddressBook_4.4. Kontact then frequently crashes.
One it crashes, It cannot be started again and akonadi refuses to do anything.

Actual Results:

Expected Results:  
$ akonadiserver stop
should just shutdown akonadi and I should be able to start kontact again.
