Upload rejected because of non-ASCII chars

I uploaded xcache and got an accept and a reject mail for it. It looks like the reject won as LP doesn't know this upload.

Here is the reject mail:

[ the same content as in the reject mail]

Note: both mails have the same Date header so I don't know in which order they were send.
