Re: How can I create a filetype association that uses the filename's extension?

Ubuntu 10.04 (Lucid)
Kernel Linux 2.632-26-generic
GNOME 2.30.2

I have, to the best of my knowledge, not run any programs that might
do heavy surgery on Gnome (cosmetic or otherwise), including not
messing with gconf-editor.

shared-mime-info is indeed installed.

I should amend my initial report:
* the .py file is, in fact, correctly identified as being of the type
"Python script (text/x-python)", and treated separately as desired.
* I observe the problem only with not-yet-known extensions, such as
*.R or *.mht. (I grepped /usr/share/mime for 'R' and 'mht' as
stand-alone words, and got no hits.)

So, the problem is "no obvious way to 'register a new/unknown
extension'," rather than the "extension ignored when determining
filetype" I initially reported. Sorry about that. Which would be a
problem with the Nautilus 'Open With' dialog rather than a problem
with Gnome itself, in which case I'd better head over to the Nautilus
mailing list. Does that sound right to you?

Cheers, and thanks
