Comment 2 for bug 86891

Bug #13373 is very similar, but it only discusses how the single default should be selected by the system (not by the user). Then it goes off on a tangent about a file picker.

It is also related to the specification https://launchpad.net/ubuntu/+spec/default-applications-firefox which is claimed as "implemented".

However, the implementation of this specification is incomplete in that it only shows the single default application that gnome would use if the user double-clicked on the file, rather than also providing the list of alternate applications that the user would get if they right-clicked on the file in e.g. nautilus.

Since there is an approved high-priority specification in Ubuntu to provide this, I think it is not [only] an upstream bug.
