Version 1.13.6+dfsg-1 of ros-rviz is marked for autoremoval from testing on Sun 05 Jan 2020. It depends (transitively) on assimp, opencolorio, affected by #937196, #944742. You should try to prevent the removal by fixing these RC bugs.
This package will soon be part of the auto-tinyxml2 transition. You might want to ensure that your package is ready for it.
