Assertion failed while updating RenderTexture

I'm currently trying to implement an inventory window in my RPG using PLSM2, with a render texture displaying only the character. So I have a RenderTargetListener that moves the character entity to a special render queue, and renders only that queue. It works but sometimes the update of the render texture crash in PLSM2 while I'm moving the main camera (not the render target one). It crashes with an assertion failed here (latest CVS for Ogre & PLSM2) :

VisibilityData *OcclusionElement::getNodeData(PagingLandScapeOctreeCamera *cam)
{
assert (nodeDataPerCam.find(cam->getId()) != nodeDataPerCam.end());
return nodeDataPerCam[cam->getId()];
}

Stack trace :

I've debugged enough to know that it crashes while rendering my inventory render texture, but after that I'm lost... Thanks in advance for any help!

did you enable occlusion culling on that camera ?
(CHC)

I've never set any PLSM2 specific option on the cameras. For culling, I just have HorizonVisibilityComputing=yes in the config file (but it still crash if I disable it).

is _VISIBILITYDEBUG defined ?
If yes try to undefine it.
Should be in project option preprocessor if on win32.

Thanks, I've recompiled PLSM2 with _VISIBILITYDEBUG off and now it works.
