Possible bug in 2.3 with OmniCC enabled

WoW will crash to desktop with OmniCC enabled on 2.3 PTR giving the following error:

"This application has encountered a critical error:
ERROR #0 (0x85100000) Assertion Failure
Program: D:\Program Files\World of Warcraft\WowTest\WoW.exe
File: .\CSimpleRender.cpp
Line: 1980
Expr: texture

Press OK to terminate the application."

The version of OmniCC is 2.0.5. It is available at http://code.google.com/p/tullamods/

For reference, to pin it down I had disabled all my addons and slowly enabled things until I got the crash. With no OmniCC wow loads normally and I can play. With OmniCC wow will crash to desktop.

To be 100% sure I disabled all mods except OmniCC (and OmniCC Options) and again it crashed to desktop with the exact same error. Disabling OmniCC Options while leaving OmniCC enabled gives the same result.

I don't know if this is a bug with OmniCC or something with the current test server build but it seemed worth posting regardless.

Edit: highlighted the error message
