ajdesignco on "[Plugin: Jetpack by WordPress.com] Catchable Fatal Error after Jetpack update"

After updating Jetpack to v2.7, I noticed an error when viewing several (not all) pages on my site. Here is the text of the error:

Warning: preg_match() expects parameter 2 to be string, object given in /[removed]/[removed]/public_html/wp-includes/post-template.php on line 199

Catchable fatal error: Object of class WP_Post could not be converted to string in /[removed]/[removed]/public_html/wp-includes/post-template.php on line 217

When I roll back Jetpack 2.5, I don't get the error.

I can't link to the site yet...it's not live. I'm working with a maintenance mode plugin.

Any ideas?
