bug#2779: 23.0.91; python-load-file in python.el does not seem to work

I've ran inferior Python in 23.0.91. Python-load-file (C-c C-l) does
not seem to do anything. I do get

  Fontifying *Python*<2>... (regexps...........)
  menu-bar Python Import/reload file
  /home/mhuhtala/test/test.py loaded

in *Messages* but the module that was supposed to be loaded never
appears in the Python session and all I get is NameErrors if I try to
use it.

This is on Fedora 10 (x86) with Python 2.5.2 and glibc 2.9-3. I
compiled both Emacs versions on the system with GCC 4.3.2-7.

Doing the same with the same Python file in Fedora 7 and its Emacs 22
does work as expected.
