As lup said, as a developer you can get rid of this error by disabling "Enable source maps" in Chrome settings.
This error apparently only shows up when using the "DevTools" (Inspect Element etc.) as it's an "interpretation map" for minified code from what I understand.
This means that any regular user/visitor will never be bothered by this error, provided they won't use the DevTools, and functionality and usability will not be affected.
Clearly not a WordPress bug, no matter how fresh or old the install is, clean or jam-packed with plugins.
