Patch against git 6ec210989fa10847091f06fcfcab77dd07618dff
Mesa crashes instead of returning GL_INVALID_ENUM when GL_NONE is passed as an argument to glReadBuffer.
Attached is a patch to achieve the desired behavior.
Can you post the backtrace? GL_NONE is a valid value for glReadBuffer() and there seems toe be plenty of Piglit tests using this so you might be hitting some corner case here.
