Ok now was too intimidated 
Looking closer I see that indeed there happens an error in GEANE somehow and then I get out a zero state.
The intialization seems to work. There are valid(?) parameters fed to Geane.
Andrea could you check this:
(qp=-2 Dqp=0.1834
TV=0.8391 DTV=0.1526
TW=-0.001362 DTW=0.02911
V=0 DV=0.8391
W=0 DW=1)
