Bug 224434

Description of problem:
When importing a gpg key, yum doesn't honour the http_proxy setting from yum.conf

Version-Release number of selected component (if applicable):
yum-3.0.3-1.fc6

How reproducible:
Everytime

Steps to Reproduce:
1.Add a repo file for a new repo which gontains a gpgkey line
2.yum install some package from that repo
3.yum will try and fetch the gpg key, but will fail, as it doesn't use the
http_proxy setting.
  
Actual results:
gpgkey is not installed

Expected results:
gpgkey installed

But then setting http_proxy shell variable, it works:
