The following problem is appears on the upgrade of libgtk2.0-0 from 2.24.6-2 to 2.24.7-1.
It only occurs using the gtk backends (not qt,wx or tk).

Whenever I close a figure either by simply closing the window, or using
the close() function, a segmentation fault kills the python interpreter
and brings me back to the unix command line.
