Comment 12 for bug 721136

@Lukas: (i) GraphCut is absolutely unchanged in 6d6c88dc,
(ii) after its recent re-implementation it is again WIP
according to its author.

Please run with NFT only to see whether this fundamental
step now works any better. BTW, GraphCut uses NFT as an
educated guess.

If you have a reasonably sized set of images, I'd be
interested in looking at the problem myself.

THX for testing!
