I'd still love to get a test case code if you can replicate the error
with libMesh 1.2... or even if you can boil the problem down to a
short code with 0.9.5; I can see if it replicates on newer libMesh or
not myself.  Now that you've discovered more about the problem it's
looking more likely to me that it's in the category "corner case we
should support but don't" rather than "bug we fixed a year ago that
you're just not up to date on yet".

However, if you're too busy I understand; it's definitely not *your*
problem anymore.  Even if there is a current bug with Gmsh loading of
multi-manifold meshes, that's only applicable to people who *want*
multi-manifold meshes, and if you don't want a combined volume +
surface mesh then "remove the triangles" is the correct way to avoid
getting one.

Thanks,
