I'm still trying to troubleshoot this. I took the backup from before the problem started and installed it on a test server. I then started doing updates. First the Drupal 7.97 to 7.98 update - that worked fine. Then I started with modules, one at a time. When I got to the Metatag module the problem appeared. Any ideas why updating to the 7.x-1.32 version of Metatag would cause this error?
That's interesting. I see that file and see the error message in it. But the failure occurs even if I do not add a thumbnail image to the new content item.

@mandclu This appears to only have been fixed in the 7.x-2.x release. Can you also update the 7.x-1.x release as well? Thank You.
@Anybody - I contacted him directly. No reply yet.
Just experience this issue when updating an older D7 site. Can someone explain how to implement Daniel's patch above? Thank You.
