Issue description

image Whenever I run any project, even empty ones, I get these 4 errors about input mapping. They are as follows:

E 0:00:00:0053 parse_mapping: Invalid device mapping entry "x:" in mapping: 03000000790000004318000000000000,dev:gc:GameCube,platform:Windows,a:b1,b:b2,y:b3,x:,start:b9,guide:,back:,leftstick:,rightstick:b0,leftshoulder:b4,rightshoulder:b7,dpup:h0.1,dpleft:h0.8,dpdown:h0.4,dpright:h0.2,leftx:a0,lefty:a1,rightx:a5,righty:a2,lefttrigger:a3,righttrigger:a4, <C++ Error> Condition "output.length() < 1 || input.length() < 2" is true.

This only happens when I use the Steam version. Using the version downloaded from godotengine.org does not yield this error. I have tried rebooting and reinstalling Godot, neither of which have worked.

Steps to reproduce

  1. Install Godot from Steam
  2. Create a new project
  3. Run the project

Most likely Steam is injecting those mappings via the SDL_GAMECONTROLLERCONFIG environment variable.

I don't know if they properly respect the spec with those empty guide: etc. Entries, but we can likely skip those and consider that those buttons don't exist for these devices (which is correct).

Do you mean to just remove this error message and continue instead?
