initialization bus error

very, very often as I am attempting to plot during a python session
(using ipython) I get the error below.
I think it happens when I get an error using an pyngl routine and ngl
fails to clean up after itself.
the bus error kicks me out of my session and I have to start over again
- this is quite tiresome.

Am I doing something dumb - to my way to thinking I should never get a
bus error - if I do something stupid the code should have a more
graceful way to die. I do realize that when things like ngl are wrapped
the error occurs where it cannot be trapped by python.

Any words of wisdom?
