OK, great. Steve could you take a look at this when you get a minute
and give some feedback about whether you think this is a god idea.

Have you done the standard clean install

  > sudo python setup.py install

I recently upgraded pycxx in CVS and my first guess is you have some stale
object code lying around.

Just tried the 'rm -fr ...../site-packages/matplotlib', and I still get the same behavior. Also, if that were the cause, then shouldn't it also crash outside of ipython as well?

I should note that I'v also seen this same crash with 0.83.2 official.

I haven't bothered to track it down, because I hardly ever use GTK except when testing for problems on the list.

It may not happen outside of ipython, if somehow the crash is triggered by the threading tricks which ipython uses to enable GTK interactive use. Nasty...
