[BUG] Call to a member function get() GKMenu.php line 110

Hello!

I'm using the template Postnote latest version (2.4). The main component on my page is ZOO. After I upgraded to the latest version I get the error

"Fatal error: Call to a member function get() on a non-object in .../gk_postnote/lib/menu/GKMenu.php on line 110"

The reason that I ask the question here. Is that it works with joomla natives templates. So it seems that it is a gavern and/or template bug.

Can you help me solve this error.

Joomla 1.7.3
Mysql 5.1.49
Php 5.2.6

5.3+ is recommended by Joomla! PHP version, maybe here is the problem. Do you have possibility to test it on server with PHP 5.3 ?

No problems with the PHP.

I had to readd all items in Zoo. Then it worked.
