I just submitted bug 932254.

When the angle of the corner of a shape is small enought, you notice, that the tip of the stroke is cut off. What is wierd about it, is that no matter how you rotate the object, the tip is always cut off vertical and horizontal. It seems like there was a bounding box for the object, outside of which the stroke is not drawn anymore.

Have a look at the picture I submitted with the bug report.

Take care
