Hi Johannes,
I am having the same issue, and "from mshr import *" does not seem to work.
Traceback (most recent call last):
File "cylinder_demo3D.py", line 40, in __init__
mesh=dolfin.Mesh(cylinder, 32)
File "/usr/lib/python2.7/dist-packages/dolfin/mesh/meshes.py", line 66, in
__init__
cpp.Mesh.__cppinit__(self, *args, **kwargs)
File "/usr/lib/python2.7/dist-packages/dolfin/cpp/mesh.py", line 1592, in
__init__
_mesh.Mesh_swiginit(self,_mesh.new_Mesh(*args))
RuntimeError:

I have a CSG object defined as:
pt1 = dolfin.Point(MAX_X_DIM, 0, 0)
pt2 = dolfin.Point(MIN_X_DIM, 0, 0)
cylinder = dolfin.Cylinder(pt1, pt2, 1.0)
Please let me know if there is anything I can do to fix this.
