[Brahms-dev-l] root issue

The new version of root has problems reading trees. The behaviour is peculiar.

You can take any of our dst (new or old) 
open the file by
root -l <filename>
root[1] T1->Draw("G.fTrigger")   ==. results in zero

if you instead create a script using MakeSelector("T1")
and use this script to read  file the content is correct (i.e what is expected).
Thus much analysis is uneffected but this is not good.

It seems in the dst to be an issue for the global class, while i.e. both FFS and FS branch seems fine !!!

-- the sequence
TChain*chain=new TChain("T1")
chain->AddFile("dst...")
chain->Draw("G.fTrigger")    ! DOES NOT work
chain->Process("T1.C")        --> works given non-zero values in a print
chain->Draw("G.fTrigger")      NOW WORKS.
