Hi. I'm a new user of pyode and I was trying to run the examples included the pythod-pyode-doc DEB package available in the Ubuntu repositories.

Tutorials 1 and 2 worked fine, but 3 fails every time I run it. The weird thing is that the error appears after the explosion, but not necessarily at the exact time. When it happens, the window closes and the following message is printed

ODE INTERNAL ERROR 1: assertion "bNormalizationResult" failed in _dNormalize4() [../../../../../include/ode/odemath.h]
Aborted

In the ode-users google group some information related to that assertion and normalization problems, although I don't have the required experience to fully understand the issue, and hopefully fix it.

I'm running Ubuntu 10.04 32-bit.

Thanks for your help,
German
