Comment (by pskli):

 Actually, it seems that it is not necessary to access the custom post type
 rewrite rule to trigger the fatal error.

 By visiting `http://core.wp/?my_taxonomy[]=test` — I get it too.

 The `my_taxonomy[]` array query param is the culprit here, subsequently
 triggering the `WP_Query->parse_tax_query` method.

 @oglekler can you share the custom taxonomy code you've created maybe?
