Comment 7 for bug 349255

gstreamer-properties appears to just be a nice front end for gconf-editor

run gconf-editor and go to system > system > gstreamer > default and change the setting for videosrc

(Note that this did not fix it for me, my setting in this box reads "v4l2src device="/dev/video0" ! videoscale" and I'm still getting green video in every application)

I've actually just reinstalled from a formatted drive Jaunty, and I'm still having this problem, although a friend with a what is possibly a slightly different model go it working with these instructions. (My model is MacBookPro2,2)
