JeffWaugh: Red Hat have patches, which may be upstream in the 1.5 branch, to integrate with the xdg-mime standard (instead of mailcap). On top of that, we may want to do some mailcap/xdg-mime synchronisation, so that other apps (such as mutt) can take advantage of the xdg-mime information.
MarkShuttleworth: We don't want to see the "do you want to do this by default?" box - just DOIT! If the Red Hat patches don't land, we want to hard code this. (JeffWaugh: ... or fix mailcap, by hardcoding or synchronising.)
