 get_post_type_capabilities() assumes $args->capabilities is an array and
 should check and confirm it. Otherwise a warning appears: Warning:
 array_merge() [function.array-merge]: Argument # 2 is not an array in
 /home/username/public_html/wp-includes/post.php on line 1183. I discovered
 this when I accidentally set this to null instead of array().

 Type setting it seems to clear the warning, if we want to clear the
 warning.

 {{{
 $capabilities = array_merge( $default_capabilities,
 (array)$args->capabilities );
 }}}
