Incompatibility between Dagon 1.23 and TreeCollision?

Walaber, I have a problem. When I update Dagon from 1.22 to 1.23 version my program crashes just when I use TreeCollision. The code is exactly the same, just changes the Dagon version and the exceptions just happens with 1.23 and TreeCollision.

It's an incompatibility or something similar?

I haven't updated yet... anyone else having this problem?

Don't worry, walaber. I've updated and rebuild again all the code (including ogrenewt) and the problem has gone
