Comment:

 Thanks for this bug report, sorry it took a little while to respond!

 I have not been able to replicate this issue, are you still seeing it in
 3.8 and/or trunk?

 From my exploration, I've tracked $post_type through a few layers:

 * $post_type is set to $typenow
 [here](https://core.trac.wordpress.org/browser/tags/3.8.1/src/wp-
 admin/edit.php#L15)
 * $typenow is set to $_REQUEST['post_type']
 [here](https://core.trac.wordpress.org/browser/tags/3.8.1/src/wp-
 admin/admin.php#L106)
 * $typenow is validated that is is a valid post type before being set
 [here](https://core.trac.wordpress.org/browser/tags/3.8.1/src/wp-
 admin/admin.php#L105)
 * $typenow is overriden to be the screen post_type
 [here](https://core.trac.wordpress.org/browser/tags/3.8.1/src/wp-
 admin/includes/screen.php#L504) before $post_type is set to it

 Ultimately, $post_type pretty much is ends up being set to the
 screen->post_type. In my grepping, I don't see any instance where this
 would be set to an array (it's always explicitly set to string), but if it
 were to be set to an array, it could cause problems here.

 I'd guess that this is an issue with a plugin messing with the screen post
 type.

 If this bug still exists, could you give us the output of the error? Also,
 your a generalized version of your tags and posts would be valuable.

 Thanks again for the report!
