[Gmsh] Correct .geo file ... but self-intersections in surfaces for 3D mesh ?!?

[Sacconi, Andrea]

Hi GMSH users,

I have a problem with a .geo file (which is attached). The geometry is composed of a parallelepiped without a cylinder. As you can see, the cylinder is represented by small triangular faces, since they are the results of finite element calculations, during which the cylinder moves in time. 
I can read the file without problem, but when I generate the 3D mesh, it keeps telling me that there are self-intersections in the surface mesh ... How come? All the surfaces are enumerated only once.
Could someone have a look at my file? I would really appreciate it!

Thanks in advance and congratulations for the amazing mesh generator :)
Andrea
