UIFE request for rhythmbox-ubuntuone SRU

[Rodney Dawes]

Hi all,

The "old" music store interface (which is embedded into Rhythmbox) will
be taken down on the server soon. In order to deal with this expectation
on 12.04 and 12.10, we'll want to remove the UI for this, from the
rhythmbox-ubuntuone plug-in. This change will intentionally remove the
UI, including some strings, but there are no new strings or UI that
would need to be translated or documented.

Thanks.
