dovecot - Jul 2014 - dovecot lda invalid user settings

I'm now dealing with issue with some users on mbox getting invalid user 
settings in /var/adm/messages.  /var/log/syslog has:

Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.error] lda(ejames): 
Error: user ejames: Initialization failed: Namespace '': Mail storage 
autodetection failed with home=/top/academic/Atmos/people/ejames/home
Jul 10 11:21:42 mail2 dovecot: [ID 583609 mail.crit] lda(ejames): Fatal: 
Invalid user settings. Refer to server log for more information.

I checked this users home directory and the mail folder is there and 
permissions are all correct.


I'm running in a mixed mbox and Maildir environment. I read to support 
this environment you simply comment out the mail_location lines in 
10-mail.conf file which will force dovecot to auto detect what format a 
user is using.  This worked fine in dovecot 1.2.12, but seems to failing 
here.
