My guess is Stefan's XServer is glx version 1.2 (Stefan glxinfo will
comfirm this).

Looking at libGL, it uses the X_GLXVendorPrivateWithReply request with
the vendor code X_GLXvop_GetDrawableAttributesSGIX when the server
version is < 1.3 (otherwise it uses the X_GLXGetDrawableAttributes
request).  Mesa doesn't support this vendor code so the request fails.
You probably need to catch this error and take the appropiate action
if it fails.
