Description of problem:
I had an error in my configuration. yum displayed:
Options Error: Not a boolean: 9

I need to ask on IRC to find the error. It was just a line "enabled=9" in one repository in /etc/yum.repos.de

I can imagine many people that are as stupid as i am ;) will have the same problem. But help would be possible! 

Version-Release number of selected component (if applicable):
yum-2.2.0-0.fc3

How reproducible:
Always

Steps to Reproduce:
1. change a line enabled=1 to enabled=9
2. make something like yum check-update
  

Actual Results:  yum does not respond but prints 
"Options Error: Not a boolean: 9"
and the help

Expected Results:  print something like:
"error in repository /etc/yum.repos.d/dag.repo line 4:
enabled=9 Options Error: Not a boolean: 9"
