Description of problem:
firstboot gives a backtrace when it is run from 

Version-Release number of selected component (if applicable):
firstboot-1.4.35-4.fc8

How reproducible:
every time

Steps to Reproduce:
1. run firstboot
  
Actual results:
Error dialog appears with subtitle:
"An error has occurred in the Firewall module."

Traceback (most recent call last):
  File "/usr/share/firstboot/firstbootWindow.py", line 497, in loadModules
    result = module.launch()
  File "/usr/share/firstboot/modules/securitylevel.py", line 591, in launch
    self.readFile()
  File "/usr/share/firstboot/modules/securitylevel.py", line 431, in readFile
    self.parseArgList(map(lambda x: x.rstrip(), lines))
  File "/usr/share/firstboot/modules/securitylevel.py", line 354, in parseArgList
    self.firewall_activated()
  File "/usr/share/firstboot/modules/securitylevel.py", line 205, in
firewall_activated
    self.setDirty(True)
  File "/usr/share/firstboot/modules/securitylevel.py", line 570, in setDirty
    self.checkDirty()
  File "/usr/share/firstboot/modules/securitylevel.py", line 576, in checkDirty
    self.applyButton.set_sensitive(True)
AttributeError: childWindow instance has no attribute 'applyButton'

Expected results:
No backtrace.

Additional info:
Perhaps this should be refiled against system-config-securitylevel
though it runs ok.  (BTW I was wondering why firstboot needs to make a symlink
to the system-config-securitylevel python dir and keeps it own copy of
securitylevel.pyc?)
