Description of problem:

After upgrade from Fedora19 to Fedora20 the package python-matplotlib-qt4 is not installed, though it seems to be required by the module pyplot present in python-matplotlib.

Version-Release number of selected component (if applicable): 1.3.0-1.fc20.i686

Actual results:

# python 
Python 2.7.5 (default, Nov 12 2013, 16:45:58)

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>

    globals(),locals(),[backend_name])

>>> quit()

Expected results:
It should be possible to import matplotlib.pyplot without errors.

rpm -q --requires python-matplotlib
