Description Esben Lund 2007-09-21 09:43:49 CEST 
There seems to be a bug in line 443 of error_propagation/src/G4ErrorFreeTrajState.cc

Line 443:
transf[1][2] = sinpPre*transf[1][3];

Should probably be:
transf[1][2] = sinpPre*transf[1][2];

This is indeed a bug. Thanks for spoting it (unluckyly in all my tests this variable was 0 or very close, so I have never realized of it)
