 This isn't exactly a bug...

 Its possible to filter '_wp_post_revision_fields' to add more fields. I am
 using this to track revisions for some meta fields.

 However the value of this must be an string otherwise you get notices when
 trying to create an autosave - as this calls `normalize_whitespace` on an
 array.

 It would be nice if this didn't completely break things. I've added a
 patch that only calls normalize whitespace if both values are strings -
 otherwise just do a simple comparison.

 If you think i'm doing_it_wrong - feel free to tell me so!

 I guess this is related to #20564 and any other meta revision fields.
