[Python-modules-team] Bug#750630: python-matplotlib: Default backend 'tkagg' broken

[Rolf Wuerdemann]

Package: python-matplotlib
Version: 1.3.1-1+b2
Followup-For: Bug #750630

Dear Maintainer,

After updating to 1.3.1-1+b2 I was unable to import pyplot from matplotlib:

>>> from matplotlib import pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/pymodules/python2.7/matplotlib/pyplot.py", line 98, in
<module>
    _backend_mod, new_figure_manager, draw_if_interactive, _show =
pylab_setup()
  File "/usr/lib/pymodules/python2.7/matplotlib/backends/__init__.py", line 28,
in pylab_setup
    globals(),locals(),[backend_name],0)
  File "/usr/lib/pymodules/python2.7/matplotlib/backends/backend_tkagg.py",
line 11, in <module>
    import matplotlib.backends.tkagg as tkagg
  File "/usr/lib/pymodules/python2.7/matplotlib/backends/tkagg.py", line 2, in
<module>
    from matplotlib.backends import _tkagg
ImportError: cannot import name _tkagg

Befor loading (and plotting) works like a charm.
