Dear users and developers
I want add new branch to my generator, I used modyfied UrQMD generator and add new branch by:
fTracks  = new TClonesArray("TLorentzVector");
manager->Register("Freezouts","FreezCoor",fTracks,kTRUE);

everything during reconstruction goes fine - I get reconstructed tracks and my additional branch, however when I try to read this by some FairRunAna i get this crash:

I don't know what is the source of such behaviour. Are there some limitations on FairROOTManager? I tried add dot at the name. When I open this file by using some primitive macro or TBrowser file seems to bee ok, but when I use FaiRunAna - I get those crashes.
In attachement I'm sending my file with data.

SOLVED
Problem was with libraries with reconstruction, I changed version of geomtry and code works!
