[Matplotlib-users] segfaults in ipython

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

Hi

I recently posted something about segfaults I get when plotting. Now 
here is a little update and I really hope someone has an idea how I can 
solve this problem.

I'm running IPython 0.6.13 on a Debian box, installed the recent mpl 
0.83.2 from source, GTKAgg backend.

1)

When I start ipython (as normal user) with the -pylab option and then say

	plot([1,2,3])

I get

In [1]: plot([1,2,3])
---------------------------------------------------------------------------
exceptions.SystemError                               Traceback (most 
recent call last)


SystemError: ../Objects/moduleobject.c:48: bad argument to internal function

2)

However when I change to root

	su
	<pwd>

	ipython -pylab

then plotting works fine!?

I have no idea where this moduleobject.c lives or to which application 
it belongs.

2)

If I try the same with the normal python interpreter

	python

	from pylab import *; ion()
	plot([1,2,3])

a plot window pops up but shows no picture (no matter if I'm root or not).


I'll appreciate any hints. Thanx!!

cheers,
steve
