I think this is all about the case where no mimeapps.list gives any preferred application for the mimetype - how should the launcher choose a default default application.

Of course, one answer is to say that part of the distro's role is defining default preferences in a mimeapps.lst so this doesn't come up, but there will always be cases it doesn't cover.
