[Dovecot] Asserion Failure in Current CVS

[Todd Burroughs]

Just installed the version from CVS as of Oct. 27.

I noticed three problems quite quickly:

Still seeing "(imap) killed with signal 14"

My INBOX closed with "access error" after reading it for a bit.  There's
nothing in the logs or anything, but this hasn't happened for quite a
while now.  There where quite a lot of incoming messages at the time and
I was marking messages as deleted using pine.  After reverting to the
last version of dovecot that I was using and restarting pine, it opened
quickly (no reindexing) and the deleted emails where marked as deleted.
I don't know if this helps much ;-)

The rest is a backtrace, etc. of an assertion failure:

dovecot: Oct 27 16:58:12 Error:  13481 imap(username): file
mbox-sync-rewrite.c: line 393 (mbox_sync_read_and_move): assertion failed:
(need_space == (uoff_t)-mails[idx].space)

dovecot: Oct 27 16:58:29 Error: child 13481 (imap) killed with signal 6
