----
3) Round table
3.1 Wouter: DDG4 particle handler has SEGV. Problematic are "stable" particles which decay
and are given to Geant4. These are double-deleted and cause problems. The solution is to add
these to the rejection list so that they are excluded from Geant4 processing.
3.2 Carl: NTR
3.2 Andre: some plugin problems still to be understood.
3.3 Sylvester: NTR
3.4 Frank: Interest in GFlash
4) AOB
