Undefined index in lib/Registry.php - getGraphicsPath()

[rsafran@gothambroadband.com]

Greetings,

I installed the latest Horde/IMP/Turba source from CVS.  Very nice.  

I experienced a problem with the getGraphicsPath function 
in /horde/lib/Registry.php.  I was getting an undefined index warning (but I 
don't know which value was undefined) which caused the pretty pictures to 
disappear.  I couldn't tell if this was a config error on my part or 
a "behavior".  I rewrote the function as follows.  

   /**
     * Query the path to the graphics webpath for any registered
     * Horde application.
     *
     * @param string $app The name of the application
     * @return URL pointing to the graphics directory of the application
     */
    function getGraphicsPath( $app = '' )
    {
//        return $this->applications[(empty($app) ? $this->getApp() : $app)]
['graphics'];
        if (empty($app))  {
           $app = $this->getApp();
           if (empty($app))  {
              $app = 'horde';
           }
        }
        return $this->applications[$app]['graphics'];
    }

Since I wouldn't be surprised that this is an error in the configs, I didn't 
make it a patch.
