Bug#537695: Patch uses "sensible-browser" [2]

[Daniel Hahler]

... sensible-browser then however prefers gnome-www-browser instead of
x-www-browser, when running GNOME:

    if test -n "$GNOME_DESKTOP_SESSION_ID"; then
        if test -x /usr/bin/gnome-www-browser; then
            exec /usr/bin/gnome-www-browser "$URL"
        elif test -x /usr/bin/x-www-browser; then
            exec /usr/bin/x-www-browser "$URL"
        elif test -x /usr/bin/gnome-terminal && test -x
/usr/bin/www-browser; then
            exec /usr/bin/gnome-terminal -e "/usr/bin/www-browser \"$URL\""
        fi
    fi


Is this a bug with sensible-browser, or should the patch explicitly call
x-www-browser?

I do not get why Gnome has a special alternatives handler for a browser
anyway?!
