[Message part 1 (text/plain, inline)]

Hello,

In the attachment is a message which is displayed in Gnus with some junk
text at the beginning. It appears that the problem is in the header
X-Ham-Report. Removing this header in the incoming email fixes the
problem for me (it does not appear in further messages). This is a
header containing technical information and some unencoded UTF-8
characters (U+FFFD to be precise). Here it is with all U+FFFD characters
replaced by `?'.

~~~~~~~~~~~
X-Ham-Report: Spam detection software, running on the system
 "server2.ultrahost.us", has identified this incoming email as possible spam. 
 The original message has been attached to this so you can view it (if it
 isn't spam) or label similar future email.  If you have any questions, see

I also have mangled the sender address a bit in order to protect it from
spamming. But this shouldn't make any difference. For me it looks like
Gnus misdetects the start of message body due to this header.

I'm unable to reproduce this bug.  If I put the message in an nnmh group
and read it, the message body is displayed as expected.

What does the display look like to you?

I am sorry. It is my old cruft again. I rechecked the article and the
problem disappears after cleaning up gnus-part-display-hook. So please
ignore this bug. Next time I will check more accurately.

No problem; I'll close the bug report.

I have found the cause of my problem. It was because my function on
gnus-part-display-hook was called for head part although was intended
only for bodies. As a result, headers sometimes got corrupted.
Unfortunately, as far as I understand there is no easy way for functions
on gnus-part-display-hook to determine the type of part on which they
are running.
