Hello,

It appears that with upstream version 0.9.0 the bug is not fixed:

[9:01:09][tazle at orn][~/unsafe/pythons]% ./scipytest/bin/python -c 'from
scipy.stats.kde import gaussian_kde; gaussian_kde([1])'
Warning: invalid value encountered in divide
Traceback (most recent call last):
  File "<string>", line 1, in <module>

    self.inv_cov = linalg.inv(self.covariance)

    a1 = asarray_chkfinite(a)

    "array must not contain infs or NaNs")
ValueError: array must not contain infs or NaNs

I did not test with the actual Debian package, since I do not have
unstable installation around. However, this should not be important,
since the changelog indicates that upstream changes are what should
close #569008.
