Solution 1:

Do not use Python 3.0. The initial releases of Python 3 were somewhat experimental and had a number of serious problems that have been fixed in subsequent releases. The fixed problems include the one you're seeing which I believe was covered by Issue5196. The current release of Python 3 is 3.2.2 and is considered production-ready. You can find installers for Mac OS X here. There are two installers depending on which version of OS X you are running. If on OS X 10.6 (Snow Leopard) or 10.7 (Lion), pay particular attention to the cautions here about also installing the current version of ActiveState Tcl/Tk to be used instead of the buggy Tcl/Tk 8.5 shipped by Apple in those systems.
