perick already explained in that thread why it cannot be a solution to switch off triangle accuracy.
The mesh seems to confuse ODE (e.g. because there are anomalies in it). Though I have no idea why it works here and does not at your machine - if I get the chance I'll test it on some more machines and see if there are any troubles with it (next year ;)) - what OS are you testing it on?
I didn't want to mean that generating physics without triangle accuracy was a solution either ://.
Just pointed out that sometimes triangle accuracy is making ODE crash showing that Exception.
Just in case it helps, and this is me guessing, I suspect this can be happening when some vertex are too close to each other to the point that transforming them could result in a different topology. Sort of (if you allow me to put it this way) ode "z-fighting". I say this because I am only observing that error in very small models, for which I can observe graphical z-fighting too.
I don't know enough about jME / jMEPhyscis / ODE as to know if that could really be a problem. Maybe someone can confirm or dismiss this :?.
