[ZendTo] Chunk name missing or too long

Ask them to clear their browser cache completely. Does it behave the 
same in a Firefox "Private Window"?
What exact version of Firefox are they running, and on what OS/platform?

I haven't had complaints from anyone else about the chunked uploading 
not working, and I tested it myself on just about every browser I could 
lay my hands on.

I would be very interested to work out what's going on here...

Cheers,
Jules.
