GIO application integration with Nautilus

[Gravis <desktop-devel adaptivetime com>]

I've asked the Nautilus dev and Gnome hackers mailing list but they dont
really know much on the issue, so here I am.  By the way, I'm using
Debian and (of course) Gnome.

------------

I've written a GTK+ application that uses the GIO API for file IO
operations and I added it as the default application to open images, in
this case a jpeg. -- http://i42.tinypic.com/2yzeg4i.jpg


It works fine with Nautilus when opening files on a local
filesystem. -- http://i44.tinypic.com/t9gzye.jpg

The problem I've run into is that Nautilus will not allow me to open
files on remote filesystems (eg sftp virtually mounted file system) with
my application (doesnt appear on the context menu list). --

When I use "Open With Other Application..." it launches the program but
does not pass in any arguments.


I have no problems opening files via CLI (eg appname
sftp://user server com/dir/image.jpg ).

Does anyone know how to solve this problem?  Is there any documentation
on how to add a GIO application to Nautilus for opening remote
filesystems?

To clarify what's happening, I've made some screenshots to show my
problem in action.

As for desktop files, here is the list of files I created/modified, all
based on entries/files for GIMP.
