Notices when default post type "post" has been disabled

[dannydehaan]

Hi Guys,

I'm currently updating the WordPress installation for a client, in this install the default post type "post" is disabled. When i updated the installation to 3.5, i'm getting the following Notice:
Notice: Trying to get property of non-object in /Path/To/WordPress/wp-includes/admin-bar.php on line 366

I made a fix for that one - included in the patch -, then the following Notices came up:
Notice: Trying to get property of non-object in /Path/To/WordPress/wp-admin/menu.php on line 52
Notice: Trying to get property of non-object in /Path/To/WordPress/wp-admin/index.php on line 79

When i fixed those 2 - also included in the patch - the following notice came up:
Notice: Undefined offset: 2 in /Path/To/WordPress/wp-admin/includes/plugin.php on line 1419

The way the disabling of the post type is done, is the following:

function remove_blog_posttype() {
	global $wp_post_types;
	unset( $wp_post_types['post'] );
}

add_action( 'init', 'remove_blog_posttype' );

Deleted the first patch, made a diff from master instead of 3.5-branch
