Crash in Node::_update()

This is a continuation of the thread:
http://www.ogre3d.org/phpBB2/viewtopic.php?t=17417

I've been having crash problems since about the time that Tuan fixed the problem with the render pools growing out of hand. For reference, see:
http://www.ogre3d.org/phpBB2addons/viewtopic.php?t=331

I don't know if it's coincidence, but I hadn't updated Ogre in 3 weeks, and it was working fine until I updated PLSM.

I've verified this occurs when all my other threads are sleeping. I had thought I was changing the sceneNode tree during the render, but that doesn't appear to be the case.

Is there a possibility that something got messed up with that fix?
Is anyone else seeing these crashes, or is it just me?

I updated to the latest CVS version of both Ogre and PLSM2 this morning, and it still crashes the same way.

I don't see that to be related to my update.

Fix is really just releasing renderable when not any more needed.
No Nodes involved.

Hmmmm... I was hoping you wouldn't say that.

Back to debugging......
