Crash in ROOT Reading Delphes file

Hi

While reading a Delphes.root file (which if I open with TBrowser looks ok) via MadAnalysis framework I get this error [*] - I know that the obvious answer is to tell me to ask MadAnalysis authors, but to them looks like a linking/compiling problem… Do you happen to have any hint anyway ?

Regards

Does it work if you open it using:

TFile *f = new TFile(“Delphes.root”);

at the root prompt ?
