Maybe, you tested that on quasy-static tasks and did not get a special
condition, when it crashes.
Rotatecylinder is a really dynamic one, that is why it appears.

I think, the problem is somewhere in "division by 0", or cross-product of
null-vector.
Please, have a look at your code.

Thanks

Bug description:
When I run examples/rotatingCylinder.py with bzr2255 (default profile) I got a crash after several iterations. Seems it related with velocityBins mechanism:
