After updating this module I was unable to edit existing gallery pages, or upload new media. Files would upload but not get added to the page. Trying to edit the gallery or to add media from the library gave a server 500 error and this showed up in the PHP error logs:
[26-Nov-2012 16:29:23] PHP Fatal error: Call to undefined function file_info_file_types() in /home2/spinlan2/public_html/drupal7/sites/all/modules/media/media.module on line 1063
After several iterations of reinstalling all my modules over two days I was able to pinpoint this update as the source of the issue.
