Re: [Visualpython-users] [Matplotlib-users] segfault when running with pylab

[Mark H. <ma...@mi...>]

Self follow-up:
Rolled back to visual 0.3.2.9 and the segfault with pylab is not present 
there; both the visual object and pylab graph are rendered correctly. 
Sorry vpython, looks like the bug is due to your new beta.
