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

A few people have now reported this, but I haven't managed to reproduce it myself. So it would be nice if someone told me how..

Sorry, missed those. So here goes some more detail:
this happens when I connect to a folder (in my case Sent). I've reproduced the bug by sending the following commands directly to the imap server:
<authentication> 3 select "Sent" 4 getquotaroot "Sent" 5 UID fetch 1:* (FLAGS) 6 UID fetch 1:201 (UID RFC822.SIZE FLAGS BODY.PEEK[HEADER.FIELDS (From To Cc Subject Date Message-ID Priority X-Priority References Newsgroups In-Reply-To Content-Type)])
then the server crashes. Attached you can find an strace log made after command 5. If you need any more detail I'll be glad to give it ...
Hope this helps,
Nuno Lopes

Hi Timo, I just discovered that this bug is showing up in the folder where I archive this mailing list. I also noticed that this problem is happening on folders where I was trying the zlib plugin for maildirs (introduced in 1.1.beta5). Since this folder hasn't got any confidential mail I can make it publicly available. You can get it from:
- The whole folder (29M) http://celebrian.portugalmail.pt/mail-folder.tgz
- dovecot files (188K) http://celebrian.portugalmail.pt/mail-dovecot.tgz
These files were created after removing all dovecot files and connecting to the folder through thunderbird, sort of a clean start. I hope this can help you in reproducing the problem.
I should also send you some more data:

Thanks, fixed: http://hg.dovecot.org/dovecot/rev/ca223be145b5
Now I just hope other people seeing this assert had the same problem.. :)
