Description of problem:
When running preupgrade (both GTK and CLI interfaces) to upgrade Rawhide, it runs for a while and then throws an exception and gets stuck.

The error thrown is:
Traceback (most recent call last):
  File "/usr/share/preupgrade/preupgrade-gtk.py", line 198, in on_assistant_apply
    self._do_main()
  File "/usr/share/preupgrade/preupgrade-gtk.py", line 206, in _do_main
    self.main_preupgrade()
  File "/usr/share/preupgrade/preupgrade-gtk.py", line 349, in main_preupgrade
    self.pu.retrieve_treeinfo()
  File "/usr/lib/python2.5/site-packages/preupgrade/__init__.py", line 395, in retrieve_treeinfo
    self.instimage = cp.get('stage2', 'instimage')
  File "/usr/lib64/python2.5/ConfigParser.py", line 520, in get
    raise NoOptionError(option, section)
ConfigParser.NoOptionError: No option 'instimage' in section: 'stage2'

(its similar in the CLI version except that the file in the first few calls in the stack is preupgrade-cli).

After the exception the CLI program exists while the GTK program stays stuck with the message "downloading installer metadata: 92.5%"

Version-Release number of selected component (if applicable):
0.9.3-3.fc9.noarch

How reproducible:
Always

Steps to Reproduce:
1. run preupgrade-cli Rawhide
2. Answer Y for the upgrade confirmation
  
Actual results:
Exception thrown

Expected results:
The preupgrade should complete
