Hi Pierre,
Did you use an opensource library to fix the mesh? I have had similar
problems importing meshes into CGAL, and havent been able to find a set of
libraries to automate the process.
I would be extremely appreciative if one could point me in the direction of
code which can fix up meshes such that they can be correctly imported.

Sinan,
I tried to fix your mesh, which is pretty hectic (92239 vertices, 163118
faces, 4271 components, 6556 boundaries, genus 7708).
good luck.
