Open a magnet URI from Google Chrome in Ubuntu 9.10 Karmic

It took more searching than it warranted but to open a magnet URI in Google Chrome/Chromium browser and have it open in Transmission you need to run the following so xdg-open can ask GNome how to handle the magnet link.

Open a terminal and for the current user:-

$ gconftool-2 -t string -s /desktop/gnome/url-handlers/magnet/command "transmission %s"
$ gconftool-2 -s /desktop/gnome/url-handlers/magnet/needs_terminal false -t bool
$ gconftool-2 -t bool -s /desktop/gnome/url-handlers/magnet/enabled true
