Segfault running PyOgre on debian unstable

Hi,

I have tried installing Pyogre on debian(unstable) and it wasn't smooth. I had ogre 1.0.5 on my machine with libcegui 0.3.0. This setup ran all the demos and some of the programs i worked on from the tutorials.
These are the steps i did:

python setup.py install

This code generated the swig bindings for ogre .It gave many warnings.

But it failed for cegui with an error saying that CEGUIUDim.h was not found. Then i installed CEGUI 0.4.1 from source in /usr/local and it failed to compile for Demo4. Since it was a test i ignored it and went ahead with the installation. The installation went ok as far as the libraries were concerned. I am ok with not having CCEGUI now.

But when i ran a demo in pyogre demos, i get a seg fault.

One change i see from the ogre is that the swig is compiled with g++4.0 and IMO ogre (on debian unstale) is still on 3.x. Can this be a reason?

I also do not have an NVidia card.So this is useless on my machine. Is there a way to disable this plugin?

Cg will run on any card (or at least it will tell you that it cannot run and give you an error, not a segfault). It will detect what your card supports and run it accordingly.... The cause of the crash is probably that you don't have Cg installed. If you do have it installed then you can remove the plugin from the plugins.cfg. This is probably in /etc/ogre if you are running debian. Let me know if you have trouble finding it and I'll ask the ogre debian maintainer where that's supposed to be.

I tried unmarking the plugin in the plugins.cfg. That doesn't seem to work.

Also, i get an error much before now though i have changes nothing.The last line being:

I have also tried running the latest version of pyogre in windows, but i get a segfault on windows also.Is this a bug in latest pyogre?
