Emacs not listed in "Open with Other Application"

[.]

I'm using Ubuntu 7.10 and I have installed emacs22-gtk.

I want to open a C++ file in Emacs from Nautilus.

I right-click on the file "main.cpp" and select "Open with Other application".

I get a window which says "Open main.cpp and other files of type "C++ source code" with:" and a list of programs, but Emacs is not listed there.

I can of course get around this by selecting "Use a custom command" and entering "emacs".

With emacs23, this is no longer an issue.

That doesn't mean it's "Invalid" for package emacs22.
