http://musicbrainz.org/edit/14573184 was an edit which changed the titles of the tracks of a release.
One minute after the above edit was entered, http://musicbrainz.org/edit/14573224 was an auto-edit by Modbot to set the track lengths based on a DiscID.
Two weeks later, the first edit expires with two Yes/zero No votes, but fails on a dependency "The tracklist has changed since this edit was created"
I guess there are a couple of issues - the main one is I don't see why changing track lengths, without changing the track order or whatever, should affect changing track titles.
If there is some reason why it does, then Modbot should hold off setting tracktimes if there is an open edit to the track listing which will fail as result.
