Segfault when closing GDIDE with a platformer game opened

[victorlevasseur]

When you close GD with a C++ game using the platformer automatism opened (and being previewed previously), GD crash (it might rather be when the scene is closed).

The backtrace :

Program received signal SIGSEGV, Segmentation fault.

Looks like it was related to #77, so it was surely fixed by https://github.com/4ian/GD/commit/48b5c8aa4296e1b2f3c942ee68a53fa22cfba671

Could you let me know if it's ok? :)

[victorlevasseur]

It's working fine. ;)
