internal.factories.registerVirtualClass

Describe the problem.
Just updated our internal pymel to git trunk as 2012 and 2013 cmds have been 
updated, plus some fixes.  2011 will boot fine with this version but we get the 
following errors with newer versions.  We use these 2 methods to register 
virtual class's.  For some reason this has produced this error.  Rolling back 
the pymel version fixes this.

What Version of Maya are you using?
2012 SAP + 2013

On what operating system? (be as specific as possible and include service
packs, 64bit vs 32bit, etc)
Windows 7 x64

What Version of PyMEL are you using?
Git Trunk

What is the expected output? What do you see instead?
NA

If possible, provide a few lines of code to reproduce the problem. It helps
us if your code will reproduce the problem from a new scene.

Methods used to register our own pynodes

                    ("cgfxShader", "CgfxShader", "dependNode"),

    mat not be loaded into Maya yet that register Maya Nodes

        log.exception(Err)

    try:
        import eNodeTypes
        reload(eNodeTypes)

Does maya.cmds exhibit the same problem?
NA
