Dear Mlody,
sorry for the late answer, but I somehow did not get the
feyncalc-Forum messages automatically anymore and just
saw your bug-report today.

Yes, in 5.1beta there is a problem when calling Tr on
unsimplified expressions.

We will try to fix the bugs still this month, but in the
meantime please use, e.g.,

tr=TR[Calc[#]]&;

and then call tr instead of Tr or TR on traces.

Of course you can do other simplifications (like DiracSimplify , or even DiracSimplify2 or alike).

Sorry for the trouble,

Rolf Mertig
