Seeing this issue too, on fully updated 12.04.5 LTS. To temporarily resolve (spinning fan on laptop is driving me crazy) revert back to lightdm/liblightdm 1.2.3-0ubuntu2.5 and restart. (Synaptic: for both packages, select package, then menu Package->Force Version. Afterwards, select both packages then Package->Lock Version)

It doesn't look like it's a resurgence of #770725 since it appears as soon as lightdm is launched, not after login. Strac'ing the process doesn't give anything. If you need anything more, please ask.
