5.1.0.1 is not a release candidate. It's out there for exposure as an alpha release (the vote isn't even completed yet!)
It looks like an issue with how null attributes are treated; assigning an attribute (of a DOM Element) the value null is supposed to remove the attribute entirely but it looks like that's not happening, resulting in a later NPE while rendering.
