Custom post type disappears from menu editor after update/first install.

[CyberSpy]

To reproduce the bug:

1. Get clean 3.8.1 installation
2. Edit functions.php of 2014 theme and add at the end:

add_action( 'init', 'vocabulary_register_post_type' );
function vocabulary_register_post_type() {
	$labels = array(
			'name' 				 => 'Słowniczek',
            'singular_name' 	 => 'Pojęcie',
            'menu_name'          => 'Pojęcia',
            'name_admin_bar'     => 'Pojęcie',
            'add_new' 			 => 'Dodaj nowe pojęcie',
            'add_new_item' 		 => 'Dodaj nowe pojęcie',
            'edit_item' 		 => 'Edytuj pojęcie',
            'new_item' 			 => 'Nowe pojęcie',
            'view_item' 		 => 'Wyswietl pojęcie',
            'all_items'          => 'Wszystkie pojęcia',
            'search_items' 		 => 'Wyszukaj pojęcia',
            'parent_item_colon'	 => 'Nadrzędne książki',
            'not_found' 		 => 'Pojęć nie znaleziono',
            'not_found_in_trash' => 'Brak usuniętych pojęć'
	);
	$product_args = array(
		'public'             => true,
		'publicly_queryable' => true,
		'show_ui'            => true,
		'show_in_menu'       => true,
		'query_var'          => true,
		'rewrite'            => array( 'slug' => 'vocabulary' ),
		'capability_type'    => 'post',
		'has_archive'        => true,
		'hierarchical'       => false,
		'menu_position'      => null,
		'supports'           => array( 'title', 'editor', 'author', 'thumbnail', 'excerpt', 'comments' ),
        'labels' 			 => $labels
    );
	register_post_type( 'vocabulary', $product_args );
}

(thats just a sample code from my project)

3. Install wp, get into admin, go to Appearance -> Menus
4. Check "Screen options" - custom post type "Slowniczkek" is hidden.

Now same process but:

1. Get clean 3.8.1 installation
2. Install wp, get into admin, go to Appearance -> Menus
3. Edit functions.php of 2014 theme and add the registering process at the end of functions.php
4. Reload Appearance -> Menus - custom post type "Slowniczek" is visible.

It looks like same problem (with hiding custom post types) happens while updating to 3.8.1

Hi CyberSpy, thanks for the report.

I was unable to reproduce this in the latest trunk and/or 3.9.1.

In both scenarios, the section for the new post type was hidden — which I believe is the expected default behavior, though I don't precisely remember where that logic lives.

Are you still seeing this issue?

[CyberSpy]

The problem still exist in 3.9.2.

Scenario A:

1. I have downloaded 3.9.2 and installed (bit didn't log in).
2. I have modified functions.php of twentyfourteen template with given code.
3. I have logged in and checked Appearance -> Menus. Custom Post Type was hidden in screen options.

Scenario B:

1. I have downloaded 3.9.2, installed and logged in (or simply deleted the database of previous installation and removed changes in twentyfourteen template).
2. I have entered Appearance -> Menus - obviously Custom Post Type was ot there.
3. I have made the modification to functions.php adding Custom Post Type
4. I have reloaded Appearance -> Menus page - Custom Post Type was visible.

No movement in 2 years closing this out. Anyone can bring it back if needed.
