Can you run in GDB or similar debugger?  If so, please set a breakpoint at
_mesa_error and provide a backtrace.  From within _mesa_error, could you also
print the value of ctx->API?

>From some out-of-band communication there was a suggestion that the problem
could be because of uses of GL_PIXEL_UNPACK_BUFFER and GL_PIXEL_PACK_BUFFER in
meta.  Meta usually sets the API to API_OPENGL_COMPAT to avoid problems like
this, but it's possible that was missed.  I believe PBOs were added in OpenGL
ES 3.0, but i965GM is an OpenGL ES 2.0 part.

FWIW... I'm working on another meta related bug, and I have some patches that
may affect the code from the "meta:" tagged commits.
