Media library grid view has no results with particular taxonomy slug

[mightyturtle]

Hello,

This bug results in no media items being found in the media library admin under certain circumstances:

1. Apply the "type" taxonomy to the attachment post type.
2. Apply a type term to an attachment.
3. Click on the taxonomy page for "type" in the media admin submenu.
4. Click on the number next to the term, which links to a view of media library items.
5. List mode reveals media items correctly.
6. Select grid mode.
7. Message displayed is "No media files found."
8. Inspect the AJAX request that is supposed to retrieve media items for the view. The query is erroneously picking up the "type" taxonomy as "post_mime_type".

Hi there, welcome to WordPress Trac! Thanks for the report.

Replying to mightyturtle:

Apply the "type" taxonomy to the attachment post type.

Note that type is one of the ​reserved terms in WordPress and should not be used as a taxonomy name. Does the issue still happen with a different taxonomy name?
