I think the whole test suite should be isolated from the user's own environment, rather than this one test being changed.

It should be run with $HOME set so as not to see those settings...

$HOME is set (the test inherits from bzrlib.tests.TestCase).
That's not the problem.
The test assumes that the command used to run the test suite (including itself) was 'selftest'.

Fixed while diagnosing.
