It sure looks like what I got with a hole in the bellows. That could explain its intermittancy, as the bellows may not open exactly every time.
I know I'm dragging this thread up from the dead a bit...
But I accidentally discovered this on Flickr:

I get the impression from one of the replies that it is caused by light reflecting past the pressure plate from the red window, and the leak is startlingly like mine to look at.
Any thoughts?
Incidentally, I've mentioned elsewhere that I've found a pinhole in the bellows, but it's not in a place that makes sense for my leak - has this guy a point?
Cheers,

Thanks - it looks bigger than mine (which I struggle to find) but in much the same place. So it probably is much the same problem. Work definitely required!
Now all I need is a bit of time (whatever that is?).
