Unknown column 'civicrm_activity.source_contact_id' when using Batch Profile Update for Activities

It's possible this isn't designed to work this way, but http://issues.civicrm.org/jira/browse/CRM-12697 and http://issues.civicrm.org/jira/browse/CRM-12928 seem to point to a problem w/ source_contact_id

I was able to recreate this issue on http://drupal.demo.civicrm.org

Steps:

• Added an Activity Type using civicrm/admin/options/activity_type called "Send Brochure"
• Added a profile w/ that activity
• Added that Activity in Schedule state to a few contacts
• Used Search > Find Activities
• Select all Contacts and use Batch Profile Update for Activities
• Select the Profile you created in the earlier step. I've attached the full SQL error.
