numpy pour Python 2.7 plante

[nicolas.patrois@gmail.com]

Bonjour,

Je me débats depuis plusieurs semaines avec numpy pour Python 2.7.
Il refuse tout simplement de se charger.
Par exemple, quand gconf2 tente de se configurer :
# dpkg --configure gconf2
Paramétrage de gconf2 (3.2.6-4+b1) ...
Traceback (most recent call last):
  File "/usr/sbin/gconf-schemas", line 8, in <module>
    import sys,os,os.path,shutil,tempfile
  File "/usr/lib/python2.7/tempfile.py", line 32, in <module>
    import io as _io

    import numpy as N

  File "/usr/lib/python2.7/dist-packages/numpy/add_newdocs.py", line

    from numpy.lib import add_newdoc
  File "/usr/lib/python2.7/dist-packages/numpy/lib/__init__.py", line

    from .type_check import *
  File "/usr/lib/python2.7/dist-packages/numpy/lib/type_check.py", line

    import numpy.core.numeric as _nx
  File "/usr/lib/python2.7/dist-packages/numpy/core/__init__.py", line 
24, in <module>
    raise ImportError(msg)
ImportError: 
Importing the multiarray numpy extension module failed.  Most
likely you are trying to import a failed build of numpy.
If you're working with a numpy git repo, try `git clean -xdf` (removes 
all
files not under version control).  Otherwise reinstall numpy.

dpkg: erreur de traitement du paquet gconf2 (--configure) :
 le sous-processus script post-installation installé a retourné une 
erreur de sortie d'état 1
Des erreurs ont été rencontrées pendant l'exécution :
 gconf2

Ou alors quand je l’importe à partir de la console Python :
> python2.7

    def bget

J’ai soumis le bug à Debian (le gars m’a envoyer chier en disant que 
j’étais le seul → fermeture du rapport), j’ai mis à jour de testing 
vers unstable, j’ai réinstallé le paquet python-numpy, rien n’y fait.
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=855535 (resolved, mon 
œil)

La version pour Python 3 de numpy fonctionne très bien.

Avez-vous une idée ?
