[imp] problem with postfix undelivered message

[Kenneth Culver]

Hi,
    I'm having a problem with a postfix "undelivered for 12 hours message." The
original message was sent using IMP and contained a single jpeg as an
attachment. When I try to view the message that postfix outputs, I get this:

Fatal error: Call to a member function on a non-object in
/usr/local/apache2/mail/horde/imp/lib/MIME/Viewer/status.php on line 55

I looked at that line, and basically there's a variable "part2" that's false,
and of course when you try to call a member function of a null object, errors
occur. I think somehow IMP/horde are parsing the mail wrong. The original mail,
with mime formatting is embedded in the message from postfix as an attachment,
and the message from postfix also has mime encoding. Any idea how to fix this?
