I've applied, after fixing the gst-plugins-bad and gst1-plugins-bad
packages, in which you forgot to propagate the new dependency to the
existing Config.in comments.

Generally speaking, I find it a bit annoying that those packages start
using Rust. Not because I have anything against Rust, but because:

 (1) It limits the support to a much smaller set of architectures. For
     example, it is not longer possible to build librsvg or its reverse
     dependencies on ARMv5 platforms.

 (2) It adds a fair amount of build time.

But well, if that's upstream decision, there's not much we can do
against it.
