This is the problem. fakeroot tells the test that it is running under
root user therefore it tries to access some dirs there (which is denied
because of fakeroot). Well, we shouldn't mkdir() from our test suite
neither - will look into that.
BTW: why do you run tests under fakeroot? why not run them under your
regular user?
