media_upload_tabs filter not called for non-async upload

[leewillis77]

Steps to reproduce:

• Register a custom post type (The media uploader only seems to show tabs on non-"post" post types???)
• Add a simple filter to media_upload_tabs (See attached)
• Click to create a new post of your post type
• Click to upload/insert an image using the "add an image" link
• Note that the media uploader does not have a gallery tab (Screenshot 1)
• Switch to "Browser Uploader" rather than flash
• Browse for a file, and upload
• The media uploader is re-loaded, but this time the Gallery tab shows. (Screenshot 2). media_upload_tabs is not being called.

Uploading media using the flash uploader doesn't have this problem (Probably because the media upload is carried out via an in-page ajax replacement rather than reloading the whole uploader.)

Ignore me - not a bug...
