A couple of things leading on from this:

1) My default mail software at the moment is Kmail, if I wanted Firefox to 
open mailto: links in Kmail would I just change mozilla-thunderbird above to 
kmail?

2) I thought I'd have a look to see what else I could configure this way and 
came across sudo update-alternatives --config x-window-manager, imagine my 
surprise when I found it was defaulted to metacity. Is this what it should be 
for Kubuntu, if not why is it set as that on mine?
