Running a tracker under ZRoundup (even the updated one
that fixes the bug I filed yesterday), file uploads
don't work.  Apparently something is expecting file
data to be passed as a string, but it's getting some
sort of Zope wrapper instead...

This is with the anydbm backend, though I suspect other
backends would see similar problems:

TypeError: argument must be string or read-only buffer,
not instance

content=<ZPublisher.HTTPRequest.FileUpload instance>)

'1'): {}}, all_links=[('issue', '1', 'files', [('file',
'-1')]), ('issue', '1', 'messages', [('msg', '-1')])],
newids=None)

[...]

(oh, in case you're puzzled, it says ZRoundup.py
everywhere because the new version of that file was the
file I had lying around and used to test adding an
attachment...)
