Possible bug with MIME types in 3.3.1?

    Hi all:

    I yesterday upgraded to WordPress 3.3.1, and ever since, when I access the Media Library in the admin page, I get this warning near every video file I have uploaded:

    That line belongs to the function wp_ext2type(), and it compares a file extension to an array of authorized extensions. I finally managed to trace this error to the fact that, when called to check a video file, the second argument passed to it isn’t an array, but the string “video/webm”…

    …which happens to be added by the “minimatica_mime_types()” function to the list of allowed MIME types. I added some debugging code to that function, and the array $types that this function receives is of the form:

    So one could certainly see how just adding:

    Like the Minimatica function does, could add the wrong data to the format… And yet:

    1) The WordPress documentation says that the above is exactly the way to go to add new MIME types.
    2) The error happens in the wp_ext2type() function, which has nothing to do with MIME types. (I added some debugging code to minimatica_file_types(), and it never got called).
    3) This error does NOT happen in my development machine, which runs PHP 5.3.5. It only happens in the server, which is running PHP 5.2.17.

    I know there’s an easy workaround for this (disable that function), but I can’t help but wonder: is this a bug with Minimatica, or with WordPress? What’s going on?

    Thank you for this workaround. It will be included in the next update.
