As far as I can work out, you use "orbit_visualization_period = 10000000000" for non-periodics and the value of PR for periodics. The wiki doesn't seem up to date with 0.10.2.
After an hour puzzling out the entry for mcnaught, this at least loads. There is little point in more decimals.

You might check the location for various times with the ephemeris from Horizons. If you have a private ssystem.ini it must be in %APPDATA%\Stellarium\data or ~/.stellarium/data (Tweak the value of radius to make it more noticable.)
