Hello,
I generated an input root file from $ROOTSYS/test/Event executable. I used MakeSelector utility to generate the analysis code so that it can be run using PROOF. I am using TDSet as input file collection. Somehow, my code is crashing while reading entries from the input file.
It can be reproduced in following ways.

Could you please look into it ?
