Here is the description of the problem. The system description follows. Everytime I read my email using KMail 3.5.6, dovecot hangs up near the end. I get the following in mail.err:

IMAP(doudou): file ostream-crlf.c: line 339 (_send_istream): assertion

The attached dovecot.txt contains the end of the tcp dump (dovecot aborts just after)
