I think there must be something else going on in your code that's causing the problem.  This snippet:

Produces the (expected) output of:

=== test.mp3 ===
PRIV Frame Size: 19

Are you perhaps referring to the total tag size and not the frame size?  TagLib's ID3v2 implementation pads the end of tags so that small changes don't require rewriting the whole file.  Almost all ID3v2 implementations do that.
