[Python-modules-team] Bug#540136: python-matplotlib: 'import pylab' depends on python-tk package

[junior]

Package: python-matplotlib
Version: 0.98.5.3-2
Severity: grave
Justification: renders package unusable


'import pylab' fails on ipython. It seems to work fine after install python-tk, as
mentioned in the ImportError.

Please check out the ipython output below showing the failure:

In [2]: import pylab
