[imp] $imp['delimiter'] is unset..

[Liam Hoekenga]

So, this log seems to be filling my apache error logs..

     [Mon Aug  1 00:38:55 2005] [error] PHP Notice:  Undefined index:
     delimiter in
     /usr/local/projects/webmail/html-ssl/horde/imp/lib/Folder.php
     on line 205

Doesn't delimiter get set automatically?
Stranger yet, my php.ini file is set not to display notices.. or at least 
I believe it is.  errror_reporting is set to

     E_COMPILE_ERROR|E_ERROR|E_CORE_ERROR

any ideas here?
