Rats! :-(
I thought I'd been very careful about testing this - obviously not
careful enough.  Can this be reproduced by simply uploading a text
file over 64K in length?

I guess I need to get my test cases out.o
This is upsetting because it makes my fix a bit of a no-fix if it
loses a byte every 64K :-(

It's either a matter of making a new issue or I'll re-open bug#637865
which is the fix where I inevitably introduced this...
  http://sourceforge.net/tracker/index.php?func=detail&aid=637865&group_id=10857&atid=110857
I think a new bug but with a link back to the old one is the way to
go.

Thanks Thierry; as usual, you are a star!
