Mutt mailbox corruption during delete

[Bob Heckel <cygwin dot 20 dot bheckel at spamgourmet dot com>]

While using mutt 1.2.5i (2000-07-28) I've noticed mailbox
corruption after performing delete commands.  I thought it might
be Cygwin related since I was unable to find it mentioned on the
mutt mailing list and because textfiles are involved.

After I delete a message, the mailbox file ends up re-written with
partial 'From' lines at the start of many, but not all, of the
messages.  I think this alters mutt's recalculation of
'Content-Length:' on that message by including the partial 'From'
line.  The error cascades on the rest of the messages in the
mailbox.

Same problem occurs regardless of Unix or DOS formatted mailboxes.
My mounts are binmode. Here's my uname -a output: 
CYGWIN_NT-5.0 THEBOX 1.3.2(0.39/3/2) 2001-05-20 23:28 i686 unknown

Sample mailbox:

  From: Bob Heckel <bheckel@foobar.com>
  To: foo@foo.org
  ...snip

Any ideas would be greatly appreciated.
