I updated to the latest svn version of uvcvideo - there were a few
changes, not sure if they were applicable to my camera though.  I
haven't been able to reproduce any errors this morning, so perhaps the
bug is gone.

There doesn't appear to be anything about in dmesg. The camera works
fine with cheese[1], and xawtv.  There was some warnings thrown by
xawtv, I'm not familiar with it so I'm not sure if they're normal or
not.  I've included them below.

Cheers,

Joel
