In Cairo a stroke() or fill() consumes the path like a hungry Python :)
You have to build your drawings in steps.
1. Get a context
2. Move to a point
3. Draw stuff - usually a single shape
4. stroke() or fill () or stroke_preserve() then fill()
5. goto 2

Go find the Python cairo tutorial page 
at :http://www.tortall.net/mu/wiki/CairoTutorial and read it carefull. Make 
notes because it's not quite as obvious as it seems.
