Comment (by azrobbo):

 I can confirm this problem with a theme by StudioPress called Executive
 Pro which uses Genesis (also by StudioPress) as a parent theme.

 I have a containerized implementation of several WP sites & I just ran
 into this problem - but only on one site.

 Additional info:

 - Initially I logged into wp-admin and upgraded WP and all sites worked
 fine.
 - Later I pulled the latest WP image and relaunched all the sites with it.
 At this point the error started appearing on ONE site (but not the others)
 - Note: the  "/var/www/html" directory is mapped to persistent storage for
 each site
 - the site experiencing the error is using a 3 year old theme by
 StudioPress called Executive Pro, and it uses Genesis as a parent theme.

 Attempts to fix that site:
 - i restored the DB & user HTML from backup and it did not fix the issue
 - as a temporary fix (i hadn't seen this yet), I commented out lines
 284-285 as they don't appear to apply to a one page site.

 '''There definitely is a problem with some themes which causes a fairly
 severe issue''' - especially for an incremental release.
