Hi Grey,
I have just tested the OSG-3.2 branch and OSG svn/trunk and both load the
two .stl ( CoffeeSpoonHolder.stl and CoffeeSpoonHolder2.stl) perfectly,
with no odd lighting affects.

$ svn log ReaderWriterSTL.cpp

This means the patch will be part of OSG-3.2.1 so I'd recommend you update
to this version of the OSG.
Robert.
