Description of problem:
I was seeing these warnings when running yum update:

Warning: group Environment gnome-desktop-environment does not exist.
Warning: group Environment minimal-environment does not exist.

Therefore, I tried running  yum grouperase gnome-desktop-environment to see what would happen, whence the error.

Version-Release number of selected component:
yum-3.4.3-91.fc19
