Actually, it looks like the problem is in pycurl, since calling .close()
seems to cause the very next floating point operation to return NaN.
(In the case of add-apt-repository, that floating point operation just
happens to be in the random() call invoked from inside the
tempfile.mkdtemp() function.)
