Using openSUSE 12.1, gnome 3, AMD64, lvm-setup

Getting this message below when restarting the system (intermittent problem, not during every reboot)
It pops up just prior to the gnome login screen.

"Could not create ICE listening socket: Cannot establish any listening sockets"
and the only option is a "Log Out" button

After clicking "log out", the normal gnome login screen appears and the system appears to be fully functional.

Any suggestions about where to start troubleshooting? Have seen some aged ubuntu-threads with similar messages but none were applicable for my scenario.
