Hello,
It appears that with upstream version 0.9.0 the bug is not fixed:
[9:01:09][tazle@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>

line 341, in _compute_covariance
self.inv_cov = linalg.inv(self.covariance)
File

line 285, in inv
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.
