I decided to upgrade my VMware Horizon View client today. It still has the same kind of issues as detailed here: https://warlord0blog.wordpress.com/2016/10/21/vmware-horizon-client-for-linux/
This time around my problems were with libgstreamer components. Even though I ensured they were installed the libraries were a different version that required by the client.
On my Debian Stretch install I had 1.0 versions.
So a quick fix by linking these made the scan issues go away.
$ cd /usr/lib/x86_64-linux-gnu $ sudo ln -s libgstapp-1.0.so.0 libgstapp-0.10.so.0 $ sudo ln -s libgstbase-1.0.so.0 libgstbase-0.10.so.0 $ sudo ln -s libgstreamer-1.0.so.0 libgstreamer-0.10.so.0
