Public bug reported: Affected version 0.98.3-3ubuntu2 (I've just checked this one). The window doe not open (show) and there are any errors (even using --verbose-helpful option). In my case it was due to wrong backend in the matplotlibrc file. Workaround is to edit matplotlibrc (sudo gedit /etc/matplotlibrc) and change the backend walue from Agg to some other (in my case 'backend : GTK' worked fine).
