[horde] Bug? Conf file generator not putting quotes around values

[Ben Davis]

When I generate a conf file in any application,  it will not put quotes 
around string values. , I also get this warning at the top of the page 
after it generates it:

Notice: Undefined index: noquote in /var/www/pca/horde/lib/Config.php

Here is the code it generated:

<?php
$conf['menu']['apps'] = array();
$conf['storage']['driver'] = prefs;
$conf['rules']['userheader'] = true;
$conf['rules']['usefolderapi'] = true;
?>

Notice that $conf['storage']['driver'] = prefs should be 
$conf['storage']['driver']= 'prefs'...  this consequently disrupts the 
CSS file for some reason (it puts warnings in the output)..
Any ideas why this is happening?
