Description of problem:
I have yum-presto installed and otherwise the default config except in /etc/yum.conf instead of keepcache=0 I have keepcache=1. When installing/upgrading some packages and then later running yum -C clean all I see this wildly ugly output:

root@localhost:~# yum -C clean all                                     
Loaded plugins: presto, refresh-packagekit
