I am not a PET expert, but I suspect that the actual experts will need 
more information about what you did before the crash happened, as well 
as some basic information about your software setup.

We have two goals in this conversation: (1) explain to you how to run 
this simulation, and (2) fix our code so that when the user does 
something wrong she gets a useful error message instead of an 
embarrassing crash.

So could you let us know the following:

1. software versions, release, distro:
   - operating system (which distro/release of linux/macosx)?
   - geant4, ROOT and Qt
   - GATE

2. the main macro for your simulation (if there is any proprietary 
information in your geometry, please leave it out)

3. what command line do you use to run it? if you are running in the 
GUI, could you also tell us the commands that you gave in there?
