Description of problem:

rhnpush uses some modules that are deprecated in python-2.6. Also warns a runtimeerror. Though this does'nt the functionality of rhnpush itself, we need to clean this up so it works clean for python-2.6+ and also older versions.  

$ rhnpush --server http://rlx-2-22.rhndev.redhat.com/APP --user admin --pass redhat *.rpm -vvvvvv
