[imp] javascript problem with messages that guess MIME type...

[Amith Varghese]

Running HEAD (as of today) I am getting javascript errors that prevent me from
forwarding messages (and from auto-expanding addresses).  This only happens in
messages where IMP tries to guess the MIME type of the attachment  (for example
if a word doc is attached as a binary file and IMP guesses that it is a word
doc).  I can bounce a message to someone if needed
