Phillippe,

What is the full version number of GTK on your system (i.e., #.#.#)?

I don't think this is a matplotlib bug. It is probably a KDE
configuration problem specific to your system. See
http://forums.gentoo.org/viewtopic-t-601154.html.

You could try editing your backend_qt4.py, in the save_figure method,
to add QFileDialog.DontUseNativeDialog to the end of the list of
arguments passed to _getSaveFileName. But that is only a workaround.

[matplotlib-devel] import collections problem

2012-07-19 Thread Benjamin Root 
Working on my refactor of axes.py, I needed to use defaultdict and possibly
OrderedDict from the collections standard module.  Problem is that
matplotlib already has a collections.py module in lib/matplotlib.  This
file takes precedence in the import process and gets in my way.  Does
anybody know of any way to force the import to do what I want?  This has
completely stumped me.

Thanks,
Ben Root

Looking at http://www.python.org/dev/peps/pep-0328/ it appears that for 
2.6 and later, using

from __future__ import absolute_import

should cause "import collections" to refer to the standard library.

Good to know.  But aren't we supporting 2.5, or did we decide on 2.6?

 >=2.6 only from now on.  This is so that we can support 3.2+ in the 
same codebase.
