I suspect that a cached file is corrupt, and that the re-retrieval code
has a buglet. We ran into a couple of segfaults recently due to
unparsable replies - which correlates with this. There was a buglet in
handling those replies - but there is still the unexplained cause of
them...

The place to look, is client_side_reply.cc: 1445 - where the reply
parsing has failed.

Add some debug fluff there, or run under gdb and breakpoint it.

Then, if this code block is invoked every time you see the bug, we need
to work backwards to identify it.

A bt full would be a good place to start.

Re: the images, lets squash this bug first and see if they get magically
better.

Cheers,
Rob
