Moving back to private since my CoreDump.gz is still attached. Whoops.

I'm afraid we'll have to wait for the retracer to go over this since the Python part of the crash isn't very useful at the moment. However, I'm afraid it won't become much more useful since Ground Control has no debugging symbols and is not available in the default install, which means the retraces can't understand it.
