[Fedora-spins] Dependency check error

[Danishka Navin]

Last night the Fedora 19 based livecd build was failed due to Firefox
dependency issue.  Build was completed when I dropped Firefox from the
package list.

I used official fedora repos and remi's repo with rpmfusion repos.

This was not occurred on last month with same repos.

I have updated the base system too.

How to fix this?
