Attached is an md2 model and texture exported from Blender. It loads 
properly into mm3d (Misfit Model 3D) and Quake Model Editor 0.91 (using 
Wine). It loads in GAMBAS and shows the same properties as a working md2 
(bauul.md2), yet raises signal 11 when the Draw method is executed.

I've looked through the code for the Draw method in the cmd2model.c file 
of the gb.opengl.sge component (I don't know C sadly) and it looks 
relatively straightforward, though I can't imagine which line it's 
crashing on. Obviously the code is expecting something in my md2 file 
which isn't there, or there's something in the md2 file that the code 
was not expecting.

Ideas anyone? And Tommy, are you still alive? :)
