The other crash is no more reproducible: I deleted all files of dovecot 
and the mails and caches; re-installed rc23.

I also removed the quota plugin references from the conf.

Now I have the problems only, when the fs quota on ext3 is over, not on 
XFS? I suppose, it's not the underlying filesystem, but that the quota is 
reached at different levels, because directories count differently in the 
two systems. I used the exact same mailbox and quota settings on both XFS 
and Ext3.

The core_segv_overquota.* files are with plugin enabled, the other ones 
without the plugin (see below for the conf).
The files are created by:
gdb /usr/local/libexec/dovecot/imap $a -batch -x gdb_cmds >"$a.out" 2>"$a.err"
Hence, the *.err files are errors from gdb itself.

(BTW: How about adding Dovecot's version to the second line of the "-n" 
output?)
# /usr/local/sbin/dovecot --version
1.0.rc23
# /usr/local/sbin/dovecot -n
# /usr/local/etc/dovecot.conf
