The policycoreutils-gui RPM requires both Python 2 and Python 3. Except in very special circumstances, there is no need for one package to drag in both Python stacks. Please split your package, or remove one of the versions of sepolicy.gui. It's OK to do this in Rawhide only, however, it would be greatly appreciated if you could push it to Fedora 28 as well. If anything is unclear, or if you need any kind of assistance, you can ask on IRC (#fedora-python on Freenode), or reply here. We'll be happy to help investigating or fixing this issue!
