hardware-sensors.py crashed with ValueError in read_sensor()

Description: Ubuntu lucid (development branch)
Release: 10.04
awn-applets-c-extras - 0.3.9~bzr1944-0ubuntu1
I was expecting to see the current temperature (and to see a variance in values)
The values showing do not change. The applet detected the problem but didn't restart.
