Bug Description

[Impact] numpy has recently released a bugfix release fixing several bugs that are severe or hard to workaround.
Full changelog:

* gh-4836: partition produces wrong results for multiple selections in equal ranges
* gh-4656: Make fftpack._raw_fft threadsafe
* gh-4628: incorrect argument order to _copyto in in np.nanmax, np.nanmin
* gh-4642: Hold GIL for converting dtypes types with fields
* gh-4733: fix np.linalg.svd(b, compute_uv=False)
* gh-4853: avoid unaligned simd load on reductions on i386
* gh-4722: Fix seg fault converting empty string to object
* gh-4613: Fix lack of NULL check in array_richcompare
* gh-4774: avoid unaligned access for strided byteswap
* gh-650: Prevent division by zero when creating arrays from some buffers
* gh-4602: ifort has issues with optimization flag O2, use O1

[Test case]
the partition issue is the most severe:

python
d = np.array([0, 1, 2, 3, 4, 5, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7, 7,7, 7, 7, 7, 7, 9])
kth = [0, 3, 19, 20]
np.partition(d, kth)[kth]

output:
array([7, 3, 7, 7])

expected:
(0, 3, 7, 7)

[Regression potential]
low, the fixes where intentionally kept simple to avoid regressions.
the test coverage of numpy is good and most of its dependencies (scipy, pandas, pytables, ..) have tested the release via their own extensive testsuites.

Hello Julian, or anyone else affected,

Accepted python-numpy into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/python-numpy/1:1.8.2-0ubuntu0.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

I did find this new crash about python-numpy in the Error Tracker:

https://errors.ubuntu.com/problem/8e5582acee98219d95d45e3703a8c64c530c0e96

Is it worth worrying about?
