$childPages = get_children('post_parent='.$post->ID);
if ( $post->post_parent && !is_array($childPages))
{
}
Prior to 2.9.2 in the above code get_children() appears to return an object that returns false from is_array($childPages) when there are no child pages, now in 2.9.2 it returns true.
Is that right, or am I missing something in my code.
Any help is appreciated!

From the last release of 2.8 to the first release of 2.9, I ran into problems with get_children, too. For me, the answer was this:
As of Version 2.6, you must pass a non-empty post_type parameter (either attachment or page).

You haven't specified post_type. Curiously, its absence did not cause me any problems until 2.9 came along, despite the reference to 2.6 in the documentation.

ok so I looked at post.php and it looks like before 2.9 get_children() would return boolean false if there were no children and now it returns an empty array
