	| Hi! 
 If I run the demo and try to use geane with the kalman filter I get the following error. Somehow a 0 momentum is appearing. It appears to me to be inside CbmGeanePro, since in geaneTrackRep the values look alright. I am not sure where the bug is.
 
 Could anyone try to reproduce this, please!
 
 
   *** S/R ERPROP   IERR =    2
