The backtrace doesn't make a lot of sense, line 843 in context.c is inside a
WARN_ON(d3d) block. That said, it crashes because create_context() in
create_primary_opengl_context() fails, after which context_release() tries to
dereference the NULL context pointer. I can fix create_primary_opengl_context()
to return a proper error code instead of crashing, but the failing
context_create() call is pretty much a duplicate of bug 18490 and a few other
similar reports that all fail due to OpenGL not being allowed on the root
window.
