Null determinant cells in Netgen

Meshing a simple geometry using Netgen I obtained some null-determinant cells that crash a solver (see http://www.cfd-online.com/Forums/ope...tml#post402809)

Enclosed you can find pictures of the mesh and the file of the .brep geometry.

The white coloured cells are the null-determinant ones.

Is there anyone able to solve this problem ? Is there any guideline to follow to avoid this cells ?

More: Why did they come in such a simple case ?

Thanks.
