[Dovecot] FETCH for mailbox mailboxname UID #1 got too little data: #2 vs #3

I got it with multiple imaptest instances even with current dovecot-1.1 hg tree.

I checked the emails with that UIDs and they are actually truncated.

Some things I noted on these mails:

• they are all with MIME multipart attachments.
• the last multipart attachment is truncated
• the truncated last line is not complete
• the following line is the beginning of a new mail (From line) without any empty line after the truncated attachment.
• in "got too little data: #2 vs #3" 0 <= #2 < #3 (zero included)
• Content-Length: #4 is sometimes bigger than both #2 and #3, sometimes smaller.
