reproduced with Inkscape 0.47+devel r8909 on OS X 10.5.8
After applying the path operation 'Intersection' there is a small sub-path with two nodes outside of the expected intersection area with the rectangle. The bounding box of the intersected path is higher than the black rectangle, indicating that there is a sub-path wrongly included in the result. Switching to the node editor reveals the bug by making the nodes of the tiny fragment visible.
