[dev] Registry bug fix

[Carlos Pires]

Hello,

I'm having this error with HEAD version of Registry.php:

[20-Nov-2007 13:16:37] PHP Notice:  Indirect modification of
overloaded property Registry::$imgDir has no effect in
/fasmounts/webmail/www/cpdev.webmail.labs.sapo.pt/framework/Horde/Horde/Registry.php
on line 1059

Here's the bug fix:

             if (in_array($app, $this->_themeCache[$theme])) {

         }

Thanks.
