You have a quartic object! This seems to be the source of the 
problem...using "sturm" in it eliminates the line in my tests.
There are several other problems as well..."refraction" and "caustics" 
are no longer used in a finish{} statement, "refraction" is now "ior", 
and both are in interior{}. You have several coincident surfaces 
problems...mainly with cylinders and differences. You are missing a 
semicolon at the end of the declaration for "ft". However, the scene 
seems to render fine...but these should be fixed.
