Rerun the test under pdb:
sage: %pdb
sage: TestSuite(T).run()
...
pdb> u
and it will point you exactly to the line showing the error. You will
see something like, for element = T.an_element(), you don't have
T(element) == element (which should hold). So there must be a glitch
in the constructor or equality test. Note that this sanity check was
just added recently, so this may have already been broken for a while,
and in particular before your change.
Cheers,
Nicolas
