I created an edit to swap around the recordings of tracks 8 and 9 on disc 2 of http://musicbrainz.org/release/e6c60285-04dc-46f7-9555-f7cb9a79a37e so that the durations match correctly.

When I got to the 'edit note' page, it showed no changes. submitting the edit created http://musicbrainz.org/edit/17748486 which it appears will do nothing.

I asked reosarevok to try the same thing and it did the same for him.
