Settings Page error

looks like a couple of empty objects exist on the Inactive Logout’s Settings Page?

Idle Message Content
Notice: Trying to get property of non-object

code that triggers it is a hook;

function wpse_58501_page_can_richedit( $can )
{
    global $post;

    if (19 == $post->ID ...

maybe a empty $post object or two somewhere?

thanks in advance
