Easiest way to reproduce this is by running the [webpack tutorial](https://webpack.github.io/docs/tutorials/getting-started/) from a directory that contains parentheses in the name. This is an issue in chokidar (see https://github.com/paulmillr/chokidar/issues/533). There is a [PR open](https://github.com/paulmillr/chokidar/pull/535) to fix it. This will also be fixed if we move to another watching library, which https://github.com/webpack/watchpack/pull/41 intends to do.
