Magento My Imeta Bug fix on category save

A customer recently came to us stating their categories were not saving correctly, it turned out to be a bit of erroneous code in a 3rd party extension they were using. If you are using My_Imeta and are experiencing difficulties saving your categories, it will be due to this. It is a quick an easy fix. Open ./app/code/community/My/Imeta/Model/Catalog/Category/Observer.php Then replace
$_object = isset($observer['data_object']) ? $observer['data_object'] : $observer['object'];
$_object = $observer->getEvent()->getCategory();
