Music scopes for Oneiric or Precise

Sat Mar 31 04:39:38 UTC 2012

Great, I've merged that change and it fixes gmusicbrowser.

Guayadeque is still not showing any results in the Music Lens. It keeps
crashing: every time I open the dash, /var/log/syslog gets a new message
about unity-scope-guayadeque trying to launch apport. I've attached a
patch with the fixes I've made so far. It gets further with these fixes,
but still crashes.

I'll look at it again tomorrow.
