Comment # 1 on bug 977327 from Bj�rn Lie

vinagre changelog have the explanation

- Disable RDP support (using bcond_with, so it can easily be
  toggled). If not building with rdp support, do not:
  - pass --enable-rdp to configure
  - BuildRequire pkgconfig(freerdp)
- Drop vinagre-revert-freerdp-versionbump.patch and
  vinagre-revert-font-smoothing.patch: they are no longer
  sufficient. FreeRDP started 1.1 and 1.2 branches but refuses to
  create releases. GNOME makes use of features found in the 1.1
  branch.

----

The version of freerdp we have in openSUSE is not new enough for us to build
said support.
We can't fault the freerdp maintainer as there are no new releases, but I will
however cc the maintainer, but maintainer is in no way obliged to push a git
snapshot...

----

There are also the following upstream bugs about vinagre + freerdp to take into
account.
