# rpm -ivh --force gnome-terminal-3.6.1-1.fc18.x86_64.rpm
nice to have functionality back. what up, gnome?
now, you need to protect it from updates. first, install the yum-versionlock plugin:
# yum install yum-versionlock
next, lock the package:
# yum versionlock gnome-terminal
if you have already performed an upgrade using fedup or this is a new install, unlock the gnome-terminal-3.8.x package.
# yum versionlock delete gnome-terminal-3.8.x-y.fc19.*
check it to see if it is locking your version:
# yum versionlock list
all done.
