Description pnmanolova 2013-06-26 13:40:40 UTC 
libcheese doesn't notify its client applications when the camera device is already being used by some other application. For instance if you open gnome-control-center and open the take picture avatar dialog and afterwards start the cheese application you get a black screen with no UI indicator as to why this is happening. This might be interpreted by users as a feature failure.

Thanks for fixing this for cheese. The problem is still present for applications using the avatar-chooser though. Maybe implementing a getter which fetches the CheeseCamera being used by the avatar-chooser, so that any application using it can connect to the state-changed signal would be a reasonable solution?

I fixed the NULL state change in CheeseAvatarChooser in commit c84e1a850231fb37793f47928b3ded18b1546920 on master.
