Re: [Matplotlib-users] segfaults in ipython, mpl verbose

[Steve S. <el...@gm...>]

Hi

Ups I think I missunderstood the meaning of VERBOSE = True in setup.py 
when compiling.

When I start ipython -pylab and try to plot mpl prints a lot of mesages 
and _these_ are the ones of interest, sorry.

OK here is the output of some tests:

This was with GTKAgg. The same happens with Agg, TkAgg, GTK.

This bug really annoys me by now and I'm wondering why mpl 0.82 
installed as Debian package works.

cheers,
