Interestingly, that it not have a crash on Windows, instead its showing this message

[PabloNeirotti]

I have the same issue. When I rename a folder in my project, it would seem to rename the folder in the background but the app gets stuck and then crash.

In my case the rename was completely different, not just a change in case, but also crashing.

Running macOS Mojave (latest - 10.14.2)

[nicktheway]

Note that if there is no scene opened, the rename is successful and there is no crush (for me at least on macOS Mojave 10.14.5)

Still reproducible with Godot 3.2.2

Steps to reproduce:

1. Download and open project from first post
2. With help CTRL + SHIFT + O open all scenes
3. Rename Shapes folder to shapes or any other name
4. Crash
