Google Docs Api v3 upload zip permissions

According to the docs a开发者_JAVA技巧ny file type can now be uploaded to Google Docs, however my upload script always returns:

403 You do not have permission to perform this operation.

It works fine with plain text documents and version 1 (not 3 as below). I'm trying to upload a tar.gz with mime type "application/x-gzip". I have a feeling it's the mime that's kicking it out. I also have the convert parameter set to false.

I'm using Zend Framework to do this but setting the version (GET parameter v) to 3 (1 won't let this work).

This is the code, very simple:

    $client = Zend_Gdata_ClientLogin::getHttpClient(self::USER, self::PASS, Zend_Gdata_Docs::AUTH_SERVICE_NAME);
    $docs = new Zend_Gdata_Docs($client);
    $result = $docs->uploadFile($latest,
                        'Backup: '.$filename,
                        'application/x-gzip',
                        'https://docs.google.com/feeds/default/private/full?v=3&convert=false');

What am I missing?

Turns out you need to use an resumable upload link, as this is the only one to support any file type.
