Description of problem: preupgrade gives a python error


Version-Release number of selected component (if applicable): latest for F-11


How reproducible: occurs for me now everytime I run preupdate


Steps to Reproduce:
1. run preupdate
  
Actual results: run through cleanly to reboot button (then reboot and install)


Expected results: produces error messages. Skips most of preupgrade steps. Shows reboot button but on reboot anaconda does not work properly.


Additional info:

previously had run preupdate and got the not-enough-space-on-/boot message

now have 300MB on /boot but it appears not to make any difference

anaconda fails as it cannot configure network
