background save fails when editing articles [unconfirmed]

[nathanallen]

• When I go to /admin/content and I click on the pencil-icon button to edit an article
• and I modify the article
• I see a 500 error in my developer console:
  POST http://localhost:3000/admin/content/autosave 500 (Internal Server Error)

My environment setup:

• ruby 2.2.5p319
• postgresql 9.4
