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

[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:

linux distribution: SLES-9 x86 using nfs
