Comment 4 for bug 1274131

Reboot.

UpdatePaused signal is sent when u-d-m sends s-i a `paused` signal. The pause signal coming from u-d-m contains only a boolean, so we don't (currently) have access to the percentage, thus we have nothing more reasonable to send in this case. Ideally, u-d-m would send us the percentage in its paused signal, but if that's not possible (either technically, or because it would be an API rev for u-d-m), then I will investigate whether it's feasible to dig that number out of information received previously from u-d-m.
