Error when reloading a page

When the dev server is started and a page is reloaded, sometimes it panics:

thread '<unnamed>' panicked at 'Error handling connection.: Io(Os { code: 32, kind: BrokenPipe, message: "Broken pipe" })', /Users/jonaseveraert/.cargo/registry/src/github.com-1ecc6299db9ec823/simple-server-0.4.0/src/lib.rs:267:26
