  Not if you recompile all 3rd party python modules the application
depends on at the same time.  Python comes with "batteries included",
thus applications seldom need 3rd party modules.  That leaves only
pygtk / gnome-python to recompile.

  There is a trick applications can do to avoid even this issue.  You
can put #!/usr/bin/python2.2 as first line in the script.  This way,
even if you install python 2.3, you'll be fine as long as you don't
uninstall python 2.2.

  Regards.
