I think we should bump the severity of this. It's very visible doing recording
with pitivi on ubuntu intrepid using a logitech uvcvideo camera. The driver
seems to be racy. After the STREAMON and QBUF ioctls, the device isn't always
ready to produce data and the first gst_v4l2src_grab_frame justs hangs
indefinitely. I understand this is partly due to broken drivers / hardware, but
uvcvideo cameras are pretty common and the fact that the pipeline blocks
forever is just wrong.
