Comment(by strk):

 But hold on a second: the input geometry is invalid:

 $ ./tests/xmltester/XMLTester --test-valid-input
 ~/Desktop/Download/bug488.xml
 /home/strk/Desktop/Download/bug488.xml: case0: test0: :  invalid geometry
 (Geometry A): Self-intersection at or near point 2.4182989742693599
 48.878099566078362

 What told you they were valid ?
