[-- Attachment #1: Type: text/plain, Size: 14744 bytes --]

Emacs coredumps when GNUS tries to read some kinds of mails.

To reproduce from 'emacs -Q', untar attached file that will create
'gnus-coredump' directory with a single mail file in it, then:

$ emacs -Q
M-x gnus
G D ;; gnus-group-enter-directory
<type directory name> RET

GNUS then tries to open this directory as group and Emacs crashes. The
backtrace and other information follows:
