gnuplot crashes when trying to zoom.

[toffyrn]

Binary package hint: python-gnuplot

Working with gnuplot in python it cant zoom in or out in the plot.
The window will only dissapear and leave the attached output in my terminal.

lsb_release -rd:

I expected that the plot should zoom in and show me a smaller part of the plot.
