sugar-control-panel -c registration fails with error

[Quozl]

Per SL 362 and some prior tickets here (#see references), the correct way to clear the registration of a laptop with a school server is a shell command in Terminal:

sugar-control-panel -c registration

However this fails in 10.1.1 and current builds because the network model source cannot be imported properly by the control panel section module:

[olpc@xo-a7-37-ad ~]$ sugar-control-panel -g registration

easy fix should be: import dbus.service

[Quozl]

yes, is a fix.

[Quozl]

dsd, please use your procedural expertise to push for review of SL 2106 and backport the fix to 0.84, thanks.

it tests out fine for me here on xo-1.5 os206.
