Could be that it can't mount /home. Did you use an existing home partition? If yes, post your /etc/fstab

This is what I have as permissions in my home directory for DCOPserver:
lrwxrwxrwx 1 markus markus 39 Jul 12 10:44 .DCOPserver_fujibox_:0 -> /home/markus/.DCOPserver_fujibox__0
-rw-r--r-- 1 markus markus 58 Jul 12 10:44 .DCOPserver_fujibox__0
