Scheduled reminders fail to run

Installation Details

WordPress 4.7.3
CiviCRM 4.7.17
CiviVolunteer 4.6-2.2.1
Angular Profiles 4.6-1.0.2
SparkPost 1.1 (verified working, bug happens with sendmail() as well)

Problem Description

I have a CiviEvent set up with a schedule reminder. The variables in the email template are:

• {event.title}
• {contact.display_name}
• {event.title}
• {event.start_date}
• {event.summary}
• {event.description}
• {event.info_url}

When the cron job runs, the email is not sent and I get this error in the scheduled jobs log and no emails are sent:

Entity: Job Action: send_reminder
Summary
Finished execution of Send Scheduled Reminders with result: Failure, Error message: Cannot build query. Variable "@selectedValues" is unknown.
Details

Parameters parsed (and passed to API method):
a:1:{s:7:"version";i:3;}

Full message:
Finished execution of Send Scheduled Reminders with result: Failure, Error message: Cannot build query. Variable "@selectedValues" is unknown.

I've tried a number of things to debug this, including turning off WordPress plugins in batches, turning off all Civi extensions.
