Comment:

 You can replicate the bug from the command line:

 {{{
 gst-launch-0.10 v4l2src ! xvimagesink
 }}}


 I was curious if the problem was with xv or with v4l2, so I did some
 additional tests:

 I tried using videotestsrc (color bars) to xv:

 {{{
 gst-launch-0.10 videotestsrc ! xvimagesink
 }}}

 this configuration does not cause the crash.

 I also tried using v4l2 with ximagesink (not x'''v'''imagesink):

 {{{
 gst-launch-0.10 v4l2src ! ximagesink
 }}}

 and this configuration also does not cause the crash.

 These two additional test cases suggest that the problem does not lie
 entirely in v4l2 (since it works with ximagesink) nor entirely in xv
 (since we can show colorbars in xv without a crash).  Hopefully these
 tests help to isolate the problem.
