Bug description:
SRU Justification
=================
[Impact]
Some webcams (cheese) don't work due to fatal error when querying attributes
that camera driver does not supported, and for them they are not working during
the OOBE capture picture step. It happens on some HP and Dell notebooks.
Devices affected include 0c45:6448 and 064e:e28a.
[Development Fix]
Already fixed in 0.10.31-1ubuntu1
[Stable Fix]
http://cgit.freedesktop.org/gstreamer/gst-plugins-good/commit/?id=c1c858f2733aba9fd8f6120656b0db20a66b6c77
[Test Case]
Test with cheese to make sure video can be recorded.
[Regression Potential]
Unlikely to have regression, as the change is minimal, by changing error into
logging a warning in the debug log and move on.
========================================
