Hi!

On my local koji infrastructure, where I use mergerepos and createrepo to deal with external repositories, I found this error when running koji regen-repo:

Traceback (most recent call last):
  File "/usr/libexec/kojid/mergerepos.orig", line 262, in <module>
    main(sys.argv[1:])
  File "/usr/libexec/kojid/mergerepos.orig", line 257, in main
    merge.write_metadata()
  File "/usr/libexec/kojid/mergerepos.orig", line 237, in write_metadata
    mdgen.doPkgMetadata()
  File "/usr/lib/python2.7/site-packages/createrepo/__init__.py", line 406, in doPkgMetadata
    if '://' in pkg: # remote
  File "/usr/lib/python2.7/site-packages/yum/packages.py", line 384, in __getitem__
    return getattr(self, key)
TypeError: getattr(): attribute name must be string

Downgrading to version 0.9.9-23.fc20 fixes this error (there's no iteration to search for :// in the pkg name)
