Additional info: I detected this when the nvidia-config-display script in the livna distribution for the nvidia drivers began crashing on start up, wiping out my xorg.conf.

This is being caused by pyxf86config allocating memory with PyObject_Malloc and then freeing it with PyMem_DEL. In python 2.5, these actually have a differences (so that the interpreter can return memory to the system). Fixed in pyxf86config-0.3.32
