check 2.6.0 release, it's fixed for me #958

Having this issue when using the bonjour npm package on an express app - kind of odd since webpack isn't included in the node_modules, package.json or the package-lock.json.

I know the npm bonjour package is included in webpack-dev-server but I'm not using this module.

@hedrick please check the latest release. I believe we have this resolved. If it's still causing an issue for you, it might be worth following up with the bonjour team as I believe we're doing everything we can on our end.
