get stuck reading the TSM file from Rhino

[vryy]

Hi
I opened and saved the rhino/simple.tsm from in Rhino v5, with T-Splines plugin installed. After that, the command below does not return, and evetually hang

RhBuilderPtr reader = TSPLINE::makePtr("simple1.tsm");

I think there are problems parsing the latest TSM correctly but does not know exactly. Anyone can look into that?

I found out that if we change "cap-type G1CAPS" to "cap-type 1" the TSM can be read normally. However, this trick does not work for some other models.
