maybe you've heard of Panda Bullet. Integrates bullet into panda3d providing a python interface.
I've been trying to use the hinge and slider constraints and found out yesterday that these mysteriously do not work on linux (but windows) and trigger this error:
enn0x, the panda bullet developer, currently has no idea what might cause that and suspects it to be some bug in bullet.:bullet(error): setWorldTransform: trans is NAN!
:bullet(error): Overflow in AABB, object removed from simulation
:bullet(error): If you can reproduce this, please email bugs@continuousphysics.com
:bullet(error): Please include above information, your Platform, version of OS.
:bullet(error): Thanks.
I'd be very happy if one of you could direct us somewhere...
