It's likely to be some kind of a floating point roundoff error, although I'm
not sure as I cannot reproduce it on my machine. Could happen only for
certain Cairo versions and/or on certain architectures, but I'm pretty
convinced that it's a bug in Cairo.

Note: if you wish to get rid of the vertices, you can use
vertex_shape="none" instead.
