Segmentation fault in EventDisplay example

[Michael Hutcheon]

Hi,
I have built a clean install of Delphes from the github version, setting up my environment using:
source /afs/cern.ch/sw/lcg/external/gcc/4.9.3/x86_64-slc6/setup.sh
source /afs/cern.ch/sw/lcg/app/releases/ROOT/6.06.00/x86_64-slc6-gcc49-opt/root/bin/thisroot.sh
And am attempting to run the EventDisplay.C root macro following this example:
https://cp3.irmp.ucl.ac.be/projects/delphes/wiki/WorkBook/EventDisplay
On a file called "output.root" (which exists and was generated with delphes).
However, the macro is producing a segmentation fault when root tries to interpret it. Please see attached the error output/call stack. Any help in fixing this would be greatly appreciated.
Cheers,
Michael
