Description:
Notice about undefined variable $stack in Title::getParentCategoryTree metod. Problem is in this code:
if($parents != '') {
....
}
because in 1.11 version metod Title::getParentCategories used by this one returned empty string, when no parent categories were found. Now (in 1.12) it returns empty array.

I propose to change condition, mentioned above to:
if($parents) {
....
}
