After V1.2 had been up for a while, I started seeing tons of syslog 
error messages like this:

Nov  5 09:11:52 mercury mail:err|error dovecot: IMAP(sdean): stat(/var/dcindx/sdean/.imap/DadEstate)
 failed: Permission denied (euid=202(sdean) egid=200(hcrc) missing +x perm: /var/dcindx)

Ownernship and Permissions are:
The index filesystem
2726 root at mercury:/var/dcindx ## ls -ald  
drwx--S--- 3946 dovecot  system       192512 Nov 05 08:59 ./

A user's directory is:

2729 root at mercury:/var/dcindx ## ls -al sdean

total 400
drwx--S---    7 sdean    sys             256 Sep 29 04:43 ./
drwx--S--- 3946 dovecot  system       192512 Nov 05 08:59 ../
drwx--S---  139 sdean    sys            8192 Sep 29 04:43 .imap/

and for the directory with the problem:

2731 root at mercury:/var/dcindx ## ls -al sdean/.imap/DadEstate
total 48
drwx--S---    2 sdean    sys             256 Sep 29 04:43 ./
drwx--S---  139 sdean    sys            8192 Sep 29 04:43 ../
-rw-------    1 sdean    sys             408 Jan 14 2009  dovecot.index
-rw-------    1 sdean    sys           18432 May 05 2009  dovecot.index.cache
-rw-------    1 sdean    sys             828 Jan 14 2009  dovecot.index.log

I switched back to V1.1, but the situation persists
