Bug#487862: gnome-terminal doesn't call x-www-browser

[Diogo 'Kovensky' Franco]

I don't think changing the default browser in the capplet isn't good
enough. It works, but it requires me to install gnome-control-panel, and
that includes the gnome desktop, the gnome panel, nautilus, and a lot of
other stuff I'll never use if I use another desktop environment with
gnome-terminal.

The update-alternatives functionality is there. I consider it a bug that
gnome-terminal disregards x-www-browser or sensible-browser as means to
select a browser in the abscence of a browser on gconf. Or actually, the
default on gnome should be set to x-www-browser and when you change
something in the capplet it changes the x-www-browser symlink, and not
gconf.
