Comment (by warner):

 I don't know if it's related, but I just tried to attach a 43kB patch to
 #166 and got an "internal trac error" with the following exception in the
 logs:

 {{{

     upload = req.args['attachment']
 KeyError: 'attachment'
 }}}

 My vague hunch is that the accept-an-attachment handler got called but
 somehow the attachment itself got lost on the way in.
