[Developers] bug: upload fails for certain strings

[John Giannandrea]

Hi
We have had some bugs around content type sniffing.
You might try setting the mime type to text/plain.
Are you uploading to sandbox?  if so could you give us
your login id or an approx log time so we can find the
actual upload entries.
Thanks.
