mm-remove-part lock-up during group exit in p0.95

[Karl Kleinpaste]

I was in nnml:mailer-daemon, had looked at a spam bounce-o-gram, whose 
original spam content was HTML.  I had just done `B DEL' to destroy it 
and was then trying to leave the group.  This error bit me hard:

Unfortunately, having `B DEL'd the message, I can't even show its
content in order to see what weirdness was going on.  This error
amounted to a total lock-up of Gnus for me, because I couldn't leave
the group by any means.  I had to manually move to the *Group* buffer
and exit uncleanly out from there; Gnus offered to let me "update
*Summary:nnml.mailer-daemon*?", to which I stupidly said yes, and got
the same error again, as it tried again erroneously to clean up.  I
finally exited Gnus by quitting without any updates.

It would have been interesting to see that message.  Judging from the
information in the backtrace, the MIME parsing code had completely,
er, missed the mark.
