GNOME 2.8 and /usr/share/application-registry?

[Toralf Lund <toralf procaptura com>]

We have an application originally developed for GNOME 2.0, that 
registers itself as handler for certain MIME types via  
/usr/share/application-registry/<app-name>.

After upgrading to GNOME 2.8, this does not seem to be listed among the 
handlers for the types in question. Or at least, I can't find references 
to it on the Nautilus right-click menu.

Should I expect my application to be registered as expected? If I 
shouldn't, why not? (Yes I realise that the MIME system is being 
changed, but there is something called "backwards compatibility")
