That is a lot of testing - so thanks for all of that work!

We do not understand the segv message when quit by Cin and could not
reproduce.  Did you ever get a dump /tmp/cinelerraxxxxx.dmp file
generated?  If not, gg has no more ideas how to debug this.  If you ever do
get dump, send it our way.

Yes, there are a few libva related libraries that have to be installed and
libva-x11 is one of them.  They are listed here:

Finally, I have tried to install UbuntuStudio16.04LTS-dvd-amd64 with

Not sure what you mean about "the result is the same".  Do you mean that
libva-x11 is missing?  If so, see the entire related list at the last URL
to see all of the packages that are needed.

> You can do a "GIT" for any previous version.  How to do this is outlined
in section 2.1.3 (create an initial clone) and 2.1.4 (build from a previous
GIT version).  If you have questions about that, just ask.
