    It says a buffer overflow was detected and it gives the stack trace showing what functions were called that led to the problem. I'm not an expert in python or gtk internals but maybe if you report it to the gtk developers they will know how to fix it.

Ok, I'll try my luck with them.  I thought that that particular combination of os, cpu, and ports would be common here, and someone could tell me if it works for them, so I'd know if there is something wrong with my setup.
