Interestingly enough, it worked if you either used MakeLineControlPoints
to directly create more than 2 points, or if you called InsertLineControlPoint
before calling AddLine. That got me thinking in the right direction, and
sure enough, the bug was in the initialisation routine.

Could you please test the following (somewhat embarrasing) patch to _lines.py:

353c353
<             self._initialised = True
---

It seems to do the trick, but I'm not sure it won't have some annoying
side effects...
