    It looks like you are creating a non-manifold point there where the circular edge and the linear edge meet.  This would create a point on the part that has infinitely small thickness.  If you were to shift the left diagonal edge of your trapezoid slightly to the left or slightly to the right, I would expect it to be fine.
