PS the v4l2src element in gst-plugins-good should disabled by default..
PPS gstreamer, gst-plugins-base and gst-plugins-good updated to latest cvs

seems like you are missing the v4l2src element. if you compile gstreamer with jhbuild you need to add the option --enable-experimental, e.g.

autogenargs='--enable-experimental ...'

gst-plugins-good compiled using --enable-experimental switch. Still crash, but only showing:

betatester@redrum:~$ cheese
0:00:01.438493963 18955 0x805c190 ERROR         GST_PIPELINE ./grammar.y:307:gst_parse_element_set: no property "queue-size" in element "source"
Segmentation fault (core dumped)

BTW it seems that my webcam is currently using v4l1, not v4l2. So I tried to run 

  gst-launch-0.10 v4lsrc queue-size=2 ! ffmpegcolorspace ! ximagesink

The element vl4src don't have the "queue-size" property... A simple 

  gst-launch-0.10 v4lsrc ! ffmpegcolorspace ! ximagesink

works fine..

PS Honeslty I was sure my cam was using v4l2... this is strange....
PPS maybe Cheese should show an error message instead crashing when can't detect/use the webcam :-)

I've just committed a fix into SVN which does not set queue-size for v4l cameras
Can you try if it works now.

Regarding your PPS: I agree. We still need to add to the cheese-webcam class a method that returns the webcams attached.
