A quick scan of the tickets did not show me anything like the following,
but I might have missed it. The attached script generates a segfault on
my ubuntu feisty system with svn numpy. Running inside of ipython, the
segfault occurs upon exiting ipython, not upon running the script.
Running the script from the command line gives the attached trace.
