nautilus scripts gone; related to mime-types problem?

[Raul Acevedo <raul cantara com>]

With 2.10, Nautilus doesn't recognize any of the scripts in
~/.gnome2/nautilus-scripts.  They don't show up in the right click menu.
(Yes, they are chmod 755; these are the same scripts that worked prior
to 2.10.)  Poking around the Nautilus email list, I saw that this might
be due to a known bug:

http://bugzilla.gnome.org/show_bug.cgi?id=142496

However, I can't fix it because in Files Types and Programs, I only see
the category "Internet Services".  I don't see other mime types I would
expect to see there, such as text and binary.  Upgrading to
shared-mime-info 0.15 doesn't help either. 

Thoughts?
