Yes, disabling that extension fixes the problem. Is it so rare that an opengl
implementation supports GL_EXT_TEXTURE_ARRAY but not glsl 1.30? The extension
spec is written against glsl 1.10.

BTW, how far is r600g from supporting glsl 1.30? AFAIK the intel driver already
advertises glsl 1.30 support.
