dovecot - Nov 2004 - (mail_index_expunge): assertion failed: (!t->view->external)

Hi all,

I was wondering if anyone's seen anything like this?

Nov 15 14:16:13 olympic dovecot: imap-login: Login: postmaster
[192.168.0.32]
Nov 15 14:17:05 olympic dovecot: IMAP(postmaster): file
mail-index-transaction.c: line 247 (mail_index_expunge): assertion
failed: (!t->view->external)
Nov 15 14:17:05 olympic dovecot: child 20184 (imap) killed with signal 6
Nov 15 14:17:19 olympic dovecot: Killed with signal 15
Nov 15 14:17:19 olympic dovecot: Dovecot v1.0-test52 starting up

I'm running (as you might have guessed) test52 on Linux (i386) using
maildirs.  The client is Thunderbird.

This only appears to be happening when viewing certain mail folders in
the IMAP account.

As a temporary fix, it seems to stop happening when I delete the
".imap*" files in the affected folder, but this is hardly an ideal
solution.

If you want any debug-type information please send me "idiots guide"
type instructions as to how to do it - I'm not a software engineer  :?

Many thanks,

Yes, I am seeing exactly the same thing.  Except that it started
happening on INBOX, which renders the client email program unusable.
Lots of lost connections, cannot select INBOX, etc. errors on the client
side.  The messages that you posted are in the dovecot server's log.

I am running test52 on Solaris.  The maildir is in the user's home
directory on a nfs server.

There are some post-test52 fixes in CVS, but I do not know if this
particular problem is addressed.

Hi

(mail_index_expunge): assertion failed: (!t->view->external) can be
fixed by deleting the /home/<user>/mail/.imap directory. It has happened
a few times with me.

Looks like I accidentally left this in test52. It was there only for 
debugging. Just remove that line entirely and it should work.

It only means that someone had expunged mail from mailbox outside 
Dovecot. If this isn't the case, there is some bug in mailbox 
synchronization..
