[Dovecot] Imap assertion (dovecot-1.1.beta13)

[Nuno Lopes]

Hi,
  I continue testing the beta versions and have seen a great improvement
over the last few ones.
On beta13 I'm seeing the following assert on some client folders:
 file index-mail.c: line 759 (index_mail_stream_destroy_callback):
assertion failed: (mail->data.destroying_stream)

If you need I can try and reproduce this in a more controled environment
to pinpoint the problem.

Thanks,
