Unsuccessful Contact Photo Uploads Due to Server Error 500

[Donald]

When uploading photos using the Google Contacts API in Objective C, the server responds to 20% of my upload requests with error 500: A temporary internal problem has occurred.  As a result, the uploaded photo doesn't appear in Gmail.  Is this a bug?  If not, what can I do so that my application's users don't experience this error?

Thank you for your help.

Here is an example server response:
