"Kernel died, restarting" when using matplotlib.pyplot

Description of your problem

IPython console dies after using matplotlib.pyplot

What steps will reproduce the problem?

1. Using matplotlib.pyplot in any way. E.g. after import matplotlib.pyplot as plt, using fig=plt.figure(1,figsize=(5,2),dpi=120) or cs=m.contourf(x,y,Z[:],cmap=plt.get_cmap('gist_earth'))

What is the expected output? What do you see instead? IPython console shows “Kernel died, restarting” and all variables are cleared.

Please provide any additional information below Not sure if this has something to do with this error, but I noticed that sometimes (not always) when I run spyder from the terminal, as soon as it opens IPython console gives the same message (“Kernel died, restarting”) and terminal shows this error: (python:2992): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed.
