Your wxPython GUI crashed:

That's a wxPython error, not the Python interpreter. The way you can 
tell is by looking at the pathname of the file that raised the 
exception:


>  File "/usr/local/lib/wxPython-3.0.1.1/lib/python2.7/site-packages/wx-3.0-osx_cocoa/wx/_core.py",

(Also, because I happen to know that the wxPython GUI is written in C++ 
so any C++ errors are from it, not the Python interpreter.)


I don't know whether this indicates corruption in the library which 
will be fixed by reinstalling, a bug in the library, or just a bug in 
your own code.
