Right, xembed-sni-proxy is officially part of Plasma5 in 5.5.
I haven't had time to port the patches yet though.

But you should be able to install the patched xembed-sni-proxy package anyway
by ignoring the conflicts.

Or switch back to Plasma 5.4.3 from the official repos, and install only my
updated xembed-sni-proxy package.
