The subpathauto module allows node subpaths like node/444/edit to be aliased to node/my-node-title/edit.

This is incompatible with the workbench_moderation redirect to node/nid/current-revision after editing a draft. Subpathauto will alias that to node/my-node-title/current-revision, and that will return Not Found.
