godot: DynamicFont causing Game Crash

Godot version: 8e82404

OS/device including version: Toaster running Mint

Issue description: get_tree().change_scene(path) causes game crash when I use a dynamic font as part of my scene in some cases. I’m not sure why it is crashing, and have not been able to create demo project to reproduce yet, but seems like it is a DynamicFont issue. What happens: my main menu is loaded at game startup. Everything is fine. I am able to navigate through a level select screen that uses DynamicFont, play a level. Crash happens when returning from level to main menu.

handle_crash: Program crashed with signal 11 Dumping the backtrace.
