detail that should have been with the attachment: I have same issue with Ubuntu 11.10 on a Lenovo laptop with built-in camera; same Gtk warning message as indicated by the OP, but NO GUI or splash screen visible as cheese is started, so no way to access any 'check config' commands.
If I turn on the 'video call' option in Skype, camera works fine; but it is usually off as link BW is 'not good enough'; only apps running when cheese app is tried are F'Fox, T'bird, & the terminal console. Running with the --gst-debug=5 log option as suggested by hychen above generates a *** 400 *** Mbyte file; after the start-up period, cheese is taking over 80% of the CPU (Celeron 2.2GHz), log file size seems static; 'nothing magic' happens. There must be a lot of duplicate info/messages in the log as it has compressed down to less than 1MByte..(attached) I see a forum post here: http://ubuntuforums.org/showthread.php?t=2068818 where the OP (squakie in the forum) states his issue (with 12.04) was solved on upgrade to 12.10. Is it possible to get a backport / work-around for earlier versions ? (limited capabilities of my platform preclude moving to 3-D desktops). Bugzilla etc in other environments I have worked with give links to the changeset that fixed whatever issue was reported originally..
