Hola Bettina,

the bug is now closed as fixed (thanks, Jürgen) so updating osgeo4w
should be enough.

If you used the standalone installer I don't know if you can update.
If you don't then do this:

1. Open C:\OSGeo4W\apps\Python25\lib\site-packages\matplotlib\backends\backend_agg.py
in notepad or any text editor. The exact path can vary if you
installed in a custom directory.

2. Look for this code (it should be lines 319, 320 and 321):

try: self._lastKey, self.renderer
except AttributeError: need_new_renderer = True
else:  need_new_renderer = (self._lastKey != key)

3. Change the second line (320) to this:
except (AttributeError, TypeError): need_new_renderer = True

4. Save changes and try again.

You can make a backup of the file before making any changes, just for
safety. But now that the bug is fixed updating osgeo4w is the right
way to go.
