I didn't see any error messages in your mail...
You can determine the backend you're set to by doing:
>>> import matplotlib
>>> matplotlib.get_backend()
'GTKAgg'
If it's 'PDF', 'Ps', 'SVG', 'Agg', or 'Cairo', it's a non-gui backend,
and therefore no gui window will be displayed.
This is usually set by the "backend" parameter in
~/.matplotlib/matplotlibrc.
Often the default backend is set to Agg if no GUI frameworks were found
at compile time. Given the recent version of matplotlib you're running,
I assume you built from source? You may need to install a gui framework
(from Fedora's yum repos should be recent enough) and rebuild matplotlib.
