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

Hi Eric,
I have still some trouble with the following example taken from openopt

starting solver ipopt (license: CPL) with problem nlp3
[PyIPOPT] Ipopt will use Hessian approximation.
[PyIPOPT] nele_hess is 0

No clue. When did it stop working?
