Repository mixing doesn’t work
Cautionary tale as to why you should not mix repositories. Dag might have some fun stuff, but it doesn’t play well with fedora.us stuff, sometimes. I had already removed it from my yum.conf, and I also got rid of the stuff in /var/cache/yum. Came home (after watching Kill Bill: Vol. 2) to a machine that had gone off with the power failure. Horror, Galeon wouldn’t start!
Good thing ~/.galeon/session_crashed.xml is nice and readable so I backed that up. The daunting task of removing GAIM, Mozilla, Epiphany, and some other depends, and then re-installing them with pristine fedora.us stuff took a few good moments. I still have 12 packages with the dag tag, so I’ll work on solving that later.
I’m sorry it doesn’t work out for you. Keep in mind though that it is actually the other way around. fedora.us doesn’t work well with other repositories (because they don’t want to).
Instead of working with the community the initial fedora.us people duplicated all the effort, leading to the current mess of incompatibilities.
However, your galeon problem is something I don’t think is caused by any of this though.
