[Python-modules-team] Bug#626659: python-matplotlib: import matplotlib.pyplot yeilds ImportError: No module named _tkagg

[Paul Strefling]

Package: python-matplotlib
Version: 0.99.3-1+b1
Severity: important

In a python2.6 shell issuing the follwing import yeilds an error:

>>> import matplotlib.pyplot
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/pymodules/python2.6/matplotlib/pyplot.py", line 78, in
<module>
    new_figure_manager, draw_if_interactive, show = pylab_setup()
  File "/usr/lib/pymodules/python2.6/matplotlib/backends/__init__.py", line 25,
in pylab_setup
    globals(),locals(),[backend_name])
  File "/usr/lib/pymodules/python2.6/matplotlib/backends/backend_tkagg.py",
line 8, in <module>
    import tkagg                 # Paint image to Tk photo blitter extension
  File "/usr/lib/pymodules/python2.6/matplotlib/backends/tkagg.py", line 1, in
<module>
    import _tkagg
ImportError: No module named _tkagg



It seems to be similair to bug #621700 which can most likley be fixed by Julian
Taylor's method:

"
to workaround this bug:
copy /etc/matplotlibrc into $HOME/.matplotlib/

change the line
backend    : TkAgg
to another backend, like GTKAgg (requires python-gtk2), Qt4Agg (requires
python-qt4)
or WXAgg (requires python-wx2.8)
"

It also seems to be similair to ubunut bug #752647:
