Queue file content crashes qrunner

[Bug Importer]

It appears that certain content contained within
mailman queue files can cause the queue runner to
crash, causing all mailing lists on the machine to
appear dead.

The relevent .msg and .db files can be found on:

http://lists.arm.linux.org.uk/2ae298a1e86267dfde7706c85fb7275f78dbf6df.msg
http://lists.arm.linux.org.uk/2ae298a1e86267dfde7706c85fb7275f78dbf6df.db

After these two files are removed from the mailman
queue directory, mailman operates as normal.

The following is an extract from the mailman error log:

Has there been any progress on this bug? Does anyone look
at these bug reports? 8(

Thanks.

A similar problem just caused our mailman queue to lock up.
For now, I just disabled this module!

File "/usr/local/mailman/Mailman/Bouncers/DSN.py", line 46,
in process
      if string.lower(msg.gettype()) <> 'multipart/report'
or \
TypeError : read-only character buffer, None

The referenced message is ill formatted. It is a MIME
multipart with no boundary parameter in its Content-Type:
header. There's little Mailman can do about this message,
but it also shouldn't crash. Attached is a fix.
