The error message and backtrace here don't prove that it's a regression in
Python: it could easily be a problem with an extension module.
Do you get this error if you compile Python 2.5 without --with-pydebug?
Is "ORBit" provided by the project at
http://sourceforge.net/projects/orbit-python/ or the one at
http://ftp.gnome.org/pub/GNOME/sources/pyorbit/? If the former, the
project's SF page says active development stopped in 2004, so there's no
way it could support Python 2.5.
