Hello, 

I'm trying to connect to a usb camera using gstreamer with the v4lsrc.  I have
the pwc and pwcx modules running and I have verified video4linux is working with
xawtv.  

My program worked correctly with gstreamer 0.6.  However, when running with
gstreamer 0.8 I am getting the error message:


(process:22384): GStreamer-CRITICAL **: file gstelement.c: line 2027
(gst_element_link_many): assertion `element_1 != NULL && element_2 != NULL' failed
/dev/video0 [v4l]: no overlay support

** (process:22384): WARNING **: v4l-conf returned 1.

It may be worth noting before showing video, xawtv reports:

> This is xawtv-3.94, running on Linux/i686 (2.6.8)
/dev/video0 [v4l]: no overlay support
v4l-conf had some trouble, trying to continue anyway
Warning: Cannot convert string "-*-ledfixed-medium-r-*--39-*-*-*-c-*-*-*" to
