exception in setShowDebugObjects()

Hi,

anybody an idea why get an exception while trying
world->setShowDebugObjects(true)

????

Of course world is initialized like this:

// Create the ODE world
_world = new OgreOde::World(mSceneMgr);

_world->setGravity(Vector3(0,-9.80665,0));
_world->setCFM(10e-5);
_world->setERP(0.8);
_world->setAutoSleep(true);
_world->setContactCorrectionVelocity(1.0);


The thing is, that with the newer version lots of code change took place, and there is simply NO showDebugObjects method in world anymore... Not sure what the new replacement is.
BTW, I guess it would be a good idea to update the wiki with the changes?
