sharing service installation has failed

Description: Ubuntu oneiric (development branch)
Release: 11.10

Expected: the service to be installed successfully and sharing to now work.

What happened: got the message "Sharing service installation has failed. Would you like to retry the installation?" Clicking retry just produces the same message

After installing samba through the USC, it seems to work fine (as in,this step is no longer needed, but sharing works).
