Comment:

 Stumbled upon a defect, which brought me to exactly this piece of code (my
 plugin stopped working after upgrade to WP 3.0 RC2 from 2.9.2). I store
 multi-dimensional hybrid array (associative array with some values being
 indexed arrays) as a post meta, and for some reason == operator fails to
 check equality of prev and new values (no idea why, I haven't heard of
 such either, quick googling haven't brought any results, but it fails for
 sure).

 The quick fix for this would probably be doing serialize first followed by
 equality check.
