bugtrack patch downloads broken

[Dominic Fandrey]

Weather I submit patches as base64 encoded attachments or inline, they get 
displayed properly, but are not downloadable:
http://www.freebsd.org/cgi/query-pr.cgi?pr=120784

Only patches that were submited using the web frontend can be downloaded:
http://www.freebsd.org/cgi/query-pr.cgi?prp=120784-1-diff&n=/patch-1.diff

Base64 does not work:
http://www.freebsd.org/cgi/query-pr.cgi?prp=120784-2-txt&n=/mount.diff

Inline doesn't work either:
http://www.freebsd.org/cgi/query-pr.cgi?prp=120784-4-diff&n=/patch-4.diff

Is this because my Emails are UTF-8 encoded? The patches only contain 
ASCII-compatible characters, so this should not be a problem. I consider it 
the main advantage of UTF-8, that it can contain ASCII text. I'd rather not 
change my configuration just to submit patches. I normally require a lot of 
international characters, so plain ASCII encoding is not an option for most 
of my mail.
