Yubina
Tested on kubuntu 16.10, crashes on try to enter a second shared scene (after exit a first scene).
On MacOS 10.9.5, crashes when exit the second scene.
I noticed before, that scenes are not "properly" closed on exit, not sure if it is related, but should be fixed anyway.
This issue is fixed with last patch, can you say me what is your ryzom client version?
