Meanwhile I really wonder how this bug, that also exists in Sage 4.0,
does *not* break many doc tests. I think a method such as
_has_coerce_map_from should return True or False, but must not raise
an error. And of course, any ring has a coercion map to itself, namely
the identity. So, the answer should be True and not TypeError.
I made it ticket #6161, a blocker.
I had no time yet to look into the sources and produce a patch,
though.
Best regards,
Simon
