Comment # 4 on bug 4628 from Nicolas Chauvet

For some reason, trying to install the scratch build has installed
chromium-libs-media-59.0.3071.104-1.fc26.x86_64 (from the base repo). Why ?
I've chromium-59.0.3071.104-1.fc26.x86_64 installed because of the previous
dependency breakage.

Also, when installing , the freeworld packages complained about
/usr/lib64/chromium-browser/libffmpeg.so not a symlink (so the alternatives are
not created).

Seems like a version check is needed somewhere.
But then this strict dependency check is annoying because it will means
breakage when the fedora package is not updated along the rpmfusion one.
