itpc association in Firefox?

[Muskiet]

I'd love to download a certain podcast but when clicking on the ITunes button I get "Firefox doesn't know how to open this address, because the protocol (itpc) isn't associated with any program."
How do I associate itpc links to a program like Rhythmbox?
I have Ubuntu 10.04 installed.

I use Miro as my Podcatcher. When I'm on a podcast site, I click on "RSS feed" and everything works just fine.

You might try Googling: itunes linux

To set this protocol, go to Alt-F2, run "gconf-editor".
The settings for itpc protocol are in /desktop/gnome/url-handlers/itpc

You can also change the itpc:// to http:// to get to the podcast.
