Wrong image shows up, when a page has the same ID as the category

Hi

I have the problem, that I have a category AND a page, which both have the same ID.

I get the thumbnail with:
$thumbnail = category_image_src( array( 'term_id' => $child->object_id, 'size' => 'full' ) , false );

I use this line in “Walker_Nav_Menu”

and now, there is not the thumbnail for the category showing up, but the thumbnail of the page.

strange?
