Debian alternative url_handler.sh

Urlview 0.9 has been installed and linked with mutt in muttrc.

Mutt is capable of displaying urlview which successfully launches
url_handler.sh located at /usr/bin/url_handler.sh with the selected url as the
argument.

url_handler.sh fails to launch firefox and there is no further output on the
terminal. The behaviour is replicated by manually launching url_handler.sh from
gnome-terminal.

Manual inspection of url_handler.sh confirms that firefox is listed first in
the variable 'x11browser' per the default installation.

In contrast the default url_handler.sh script packaged with Debian and
extracted from source works as fine when manually executed or included in a new
'.urlview'. This script is attached for comparison.
