well you might want to double check my file, but I don't see any degenerate segment in my polygons. But I thought about it, maybe it was a problem at the junction between first and last points, so I skipped a few points at the end when reading the file, and I still have this problem. I must add that this configuration works fine when I use GEOS. 

I didn't specified my system : Visual Studio 2010 on win XP, if it's of any help.

Explanation: cannot construct a degenerate segment
without looking at the file, it is highly probable that you have a
segment made of two identical points.
