[Yum] Major bug in yum 2.4.1

[Joshua Jensen]

I and my team have found what we consider to be a major bug in yum 
2.4.1.  Essentially all you have to do to trigger it is a "yum clean 
metadata", then something like install or even just check-update:

$ sudo yum check-update
Setting up repositories
(works fine)

$ sudo yum clean metadata
Cleaning up xml metadata
14 metadata files removed

$ sudo yum -d 10 check-update
Yum Version: 2.4.1
COMMAND: yum -d 10
Installroot: /
Setting up repositories
Baseurl(s) for repo: ['http://server/yum/5.00/emergency-install/i386']
Cannot open/read repomd.xml file for repository: emergency-install
Cannot find repomd.xml file for emergency-install
Error: Cannot find repomd.xml file for emergency-install


I can remove the emergency-install repo, but it just fails on the first 
repo it finds.  Essentially yum 2.4.1 fails in downloading a *new* 
repomd.xml file.  If it exists but it is old... no problem.  However if 
it is removed from a "clean all" or even just a "clean metadata" yum 
command, it won't re-create the file... and chokes because of it.

Has anyone else seen this with yum 2.4.1 ?
