Last night I uploaded an updated python3-defaults package to fix a problem
where dh_python3 was not honoring version requirements set the -V option in
debian/rules or X-Python3-Version in debian/control.
If you have a python3 module package that set a minumum version of python3 to
3.2 using one of those methods, it probably has a minimum version of 3.1.3-13~
in error. Please check your packages and consider rebuilding and uploading
(these are arch all, extensions should all be correct) so users don't try and
install them in Sqeeze by mistake.
