I didn't check the example nlp_3.py (from openopt)
regularly. So I can't tell you when it stopped.
As a workaround I have used another backend in my
matplotlibrc
#### CONFIGURATION BEGINS HERE
# the default backend; one of GTK GTKAgg GTKCairo FltkAgg
QtAgg TkAgg
# Agg Cairo GD GDK Paint PS PDF SVG Template
#backend : WXAgg
backend : TkAgg
Cheers,
Nils
