  When I install the updated library versions listed above vlc crashes. I have 
experienced this with multiple mp4 files.

  When I revert these libraries to the following older versions, it
  works correctly:

  hi  libglapi-mesa:amd64                        18.0.5-0ubuntu0~18.04.1        
              amd64        free implementation of the GL API -- shared library
  hi  libglx-mesa0:amd64                         18.0.5-0ubuntu0~18.04.1        
              amd64        free implementation of the OpenGL API -- GLX vendor 
library

  I am enclosing a log of a gdb session including a backtrace.

  Thank You.
