I'm not sure the flatpak/p11-kit problem will be so easily fixed. As I 
understand it, flatpak talks to a p11-kit server process over a socket. 
The server may have been started by something other than flatpak, so it 
might not be the fixed version.

I'm not comfortable deciding whether or not this should block the merge, so 
I'll defer to someone else who has more experience making those types of 
judgments.
