Bug 290790

Application: nepomukserver (0.2)
KDE Platform Version: 4.7.3 (4.7.3)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
OS Summary:
Distribution: Ubuntu + KUbuntu 11.10
Kernel: 3.0.0-15-generic #25-Ubuntu SMP Mon Jan 2 17:44:42 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux
	(but the problem there was before too)

Nepomukserver crashes on every logon on KDE Plasma. No error if I logon on Gnome (Unity). If I try to start it manually, then everytime nepomukserver crashes again with the same error.
I tried to remove my custom kde settings from my home folder (.kde/share/apps/nepomukserver and akonadi), but nothing to do.
I tried to start it by terminal and this is the error message:

KCrash: Application 'nepomukserver' crashing...
KCrash: Attempting to start /usr/lib/kde4/libexec/drkonqi from kdeinit
sock_file=<home-folder>/.kde/socket-<my-host-name>/kdeinit4__0
NepomukServer(3504): Communication problem with  "NepomukServer" , it probably crashed. 
Error message was:  "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "

The crash can be reproduced every time.
