 I'm seeing errors on the 'Dashboard', and 'Comments' admin pages when a
 CPT that supports comments has been deactivated (e.g. via a Plugin).

 Reported error messages are:

 {{{
 Notice: Trying to get property of non-object in C:\wamp\www\wp\wp-
 includes\capabilities.php on line 1154
 Notice: Trying to get property of non-object in C:\wamp\www\wp\wp-
 includes\capabilities.php on line 1155
 }}}

 Here is an example Plugin with steps to replicate the issue:

 1. Activate Plugin (below) to enable the CPT.
 2. Create a new 'Testimonial' and publish it to be able to leave a comment
 directly on the post edit screen.
 3. View the comment on 'Dashboard' and 'Comments' admin pages (no visible
 errors).
 4. Deactivate the Plugin and view 'Dashboard' and 'Comments' admin pages
 again. Errors are visible this time.

 {{{
 <?php
 /*
 Plugin Name: CPT comments error example
 */
 function reg_cpt() {
                 $args = array(
                         'public' => true,
                         'supports' => array( 'title', 'comments' ),
                         'labels' => array( 'name' => 'Testimonials' )
                 );
                 register_post_type( 'tml', $args );
 }
 add_action( 'init', 'reg_cpt' );
 }}}
