METS scale setter fails in ttbar on trunk

[Frank Siegert]

When the METS scale setter on trunk r16032 is used in several variations of ttbar, it gives the error messages pasted at the bottom. It doesn't make any difference whether METS__reject_unordered is active or not, and changing DecayOS to Decay also doesn't make a difference. This works without problems in 1.2.2 as long as DecayOS is used. With Decay it also gives very high %'s of "No CSS history".
