The default TkAgg backend for matplotlib dosn't work and gives the folowing error when 
pyplot is imported in both python 2.6 and 2.5

>>> import matplotlib.pyplot                                          
Traceback (most recent call last):                                    
  File "<stdin>", line 1, in <module>                                 
  File "/usr/lib/python2.6/dist-packages/matplotlib/pyplot.py", line 75, in <module>
    new_figure_manager, draw_if_interactive, show = pylab_setup()                   
  File "/usr/lib/python2.6/dist-packages/matplotlib/backends/__init__.py", line 25, in pylab_setup
    globals(),locals(),[backend_name])                                                            
  File "/usr/lib/python2.6/dist-packages/matplotlib/backends/backend_tkagg.py", line 8, in <module>
    import tkagg                 # Paint image to Tk photo blitter extension                       
  File "/usr/lib/python2.6/dist-packages/matplotlib/backends/tkagg.py", line 1, in <module>
    import _tkagg
ImportError: No module named _tkagg

However if you change the backend in /etc/matplotlibrc to QT4 (and maybe
others) everything works fine

using matplotlib 0.98.5.2-1ubuntu1 on kubuntu 9.04 alpha 5

** Affects: matplotlib (Ubuntu)
     Importance: Undecided
         Status: Confirmed
