Godot closing upon _Save branch as scene_, on Ubuntu 16.04

[diegodillenburg]

Godot version:
v2.1.4.stable.official

OS/device including version:
Ubuntu 16.04.2 LTS

Issue description:
Upon clicking on a node tree and selecting "Save Branch as Scene" Godot proceeds to saving dialogue, saves the scene, but closes afterwards.

Steps to reproduce:
Specific node tree was:

• Path2d
  • PathFollow2d
    • KinematicBody2d
      • Sprite
      • AnimationPlayer
      • CollisionShape2d

Right click on Path2d node and select "Save Branch as Scene"
P.S.: Seems to happen with this specific tree.

Minimal reproduction project:
TestProject.tar.gz

Sounds like #9367, can you provide a stacktrace too?

[akien-mga]

can you provide a stacktrace too?

Note that you can't do this with the official 2.1.4 binaries, so you will have to compile some yourself to do that. If you want to try it, check http://docs.godotengine.org/en/stable/development/compiling/compiling_for_x11.html for instructions on how to build from source and checkout the 2.1 branch (otherwise you'll be testing with Godot 3).

I'm travelling for the next couple of days, but will do as soon as I get back.
