Comment (by SergeyBiryukov):

 The warning is displayed when the post has a featured image with corrupted
 metadata: the image has a particular size, but its `height` attribute is
 empty.

 I have no objections to checking the value to avoid the warning, but it
 would be nice to find out what causes the metadata to become corrupted
 like that, as it could cause other issues elsewhere.

 @aegis123, @Abigailm: Were you able to identify any pattern in the
 affected posts? What kind of a featured image (format, size) they have?
