Thanks.

This is an old issue. It used to cause problems with Unity8 too (see bug
1535297).

A proper fix needs to come from protobuf itself, but the bug could also
be avoided if Mir or your app were willing and able to change protobuf
versions.

Bug description:
  So somewhen in last week there were made some changes in the ubuntu
  repository which effect libEGL. This lib newly uses libmirclient.so.9
  which itself uses libprotobuf-lite.so.9. The default protobuffers
  version shipped with ubuntu is 2.6.1. My application uses libgstvaapi
  which uses libEGL. My application as well uses protobuffers but I link
  it statically to version 3.0.0 due to its json compatibility. So when
  now starting the application it crashes immediately due to rivaling
  protobuffers version. This problem first occured last week somewhen.
  This makes it impossible to use libEGL/libmir and a not-default
  protobuffers version in one application. Please let me how you're
  going to deal with that.

  Best,
  Henning
