[Fluxus] build-type crash

[gabor papp]

the following script crashes after running for about 1-2 minutes. it is 
a simple build/destroy script with type primitives. can someone repeat 
this or is it only happening on my setup?

libGLU.dylib 0x970b1623 gluTessCallback + 371

Fluxus::TypePrimitive::BuildGeometry(FT_GlyphSlotRec_* const&, 
Fluxus::TypePrimitive::GlyphGeometry&, float, bool) + 80
