I can imagine why this stuff is broken... We're not using
GL_ATI_fragment_shader on your card(as intended), but there is no GLSL or ARB
fragment processing, so the opengl fixed function pipeline is still used.
However, as a leftover from some earlier developemnt state, the context manager
still enables GL_FRAGMENT_SHADER_ATI, and the driver expects us to feed it with
an ati fragment shader.

You can confirm my theory by commenting out all
glEnable(GL_FRAGMENT_SHADER_ATI) calls in context.c. That should fix the
problem. I'll send a patch.
