Yes, gnome_vfs_mime_get_extensions_list is part of the old mime API that
used the old gnome-mime-data information. It was deprecated when we
moved to the shared-mime-data info. This is since:
a) shared-mime-info uses globs, not extensions
b) Getting that data in the new system isn't very efficient

The whole mime system API is kinda weird since the initial API was
essentially exposing the old mime data file format, and then we changed
file format...
