error in arcpy sourcecode?

Trying to create any Geometry object results in this message:

Traceback (most recent call last):
File "C:\Data\Daten\Untersuchungsgebiete\FeatureClass ertstellen.py", line 15, in <module>
Point=arcpy.Point ([row[1],row[3]])
File "C:\Program Files (x86)\ArcGIS\Desktop10.2\arcpy\arcpy\arcobjects\mixins.py", line 1047, in __init__
setattr(self, attr, value)
File "C:\Program Files (x86)\ArcGIS\Desktop10.2\arcpy\arcpy\arcobjects\_base.py", line 89, in _set
return setattr(self._arc_object, attr_name, cval(val))

Any ideas whats going wrong?

Thanks a lot!
