When generating an error inside a route handler with

request.reply(Hapi.Error.internal('Error writing to the db.', err));

console output is:

Unmonitored error: hapi, internal, error
undefined

Expected stack trace instead of undefined.

After some digging I found out that the problem is most likely on hapi/lib/request.js:203

console.error('Unmonitored error: ' + item.tags.join(', '));
if (data) {
    console.error(data instanceof Error ? data.stack : data);
}

A boom object is an instance of Error, but it has no "stack" property.
