"The system network services are not compatible with this version"

[Adam Tauno Williams <awilliam whitemice org>]

I have one openSUSE 11.4 workstation [desktop] that is having problems
after upgrading to GNOME 3.

Going into system settins / network results in the warning "The system
network services are not compatible with this version."

Evolution and Empathy start but never seem to connect.  Evolution is
just checking-folders and empathy is "Connecting...".

And there is no network manager in the top-bar.

Any suggestions?
