Bug Description

I am not sure what is the key problem to put in the title (from below) , but this seems like different symptom/output from https://bugs.launchpad.net/ubuntu/+source/guvcview/+bug/1373221

Launching guvcview dies immediately, always. My camera never comes on anymore.
My laptop built-in camera also doesn't come on now with cheese, which just gives a black screen.
It used to work fine, prior to some update a few weeks ago.
