That's interesting. I wonder if that is related to the issue I found
with w1-gpio the other day?

w1-gpio is given GPIO0 as a pullup pin by the BSP so it takes control of
it for that purpose, possibly breaking the I2C bus as mentioned in your link

Issue: https://github.com/raspberrypi/linux/issues/601

My fix is here: https://github.com/raspberrypi/linux/pull/602

I'm not loading the w1-gpio at present though so I don't believe it is
causing the problem

(In fact - at any point I can run mjpg-streamer and that will work! So I
know the camera is OK...)

No problem Alex. I appreciate any thoughts at all :)

I think next I'm going to have a look at gstreamer1.0-omx and see where
that gets me...

Cheers,

Alex
