Thanks for testing.

The first test failure in logser is a known failure that I haven't
marked yet as such (the error is in numpy.random according to my
tests). The second failure, nbinom, I don't get in my test runs. Since
these are random tests, it might be an accidental failure and I might
have to add a comment or reduce the precision of the test. Could you
run the tests again, just scipy.stats, to see if the second test fails
each time or just accidentally? I will also check again, that there
are no problems left with nbinom.

By the way, these are failures because of new tests with more coverage
and not because of new bugs.
