Does crash mean segfault?  If so, please file a report against one
of the relevant packages (cheese or the appropriate gstreamer lib)
so the error handling can be fixed.

Thanks.  Please attach full "dmesg" output from booting and
reproducing the problem.

If you get a chance to try 3.4.y from experimental, that would be
interesting, too.  If it reproduces the problem, we can get help from
upstream.

Hope that helps,
