winston.handleExceptions submits 'false' to papertrail.

Hi, I’m trying to use winston-papertrail to log nodejs/express unhandled exceptions but they show up as “false” in papertrail. Code snippet:

var winston = require('winston');
winston.handleExceptions(
  new winston.transports.Papertrail({
        host: 'xxx',
        port: xxx,
        hostname: 'xxx',
        inlineMeta: true
    })            
);

Then I throw an exception without catching it, like this:

throw Error('boo');

After spending some time looking into it I could find out that it looks like “level” is being passed as undefined into:

Papertrail.prototype.sendMessage = function (hostname, program, level, message) {

This is live on NPM in version 1.0.3.

If you’re reading this message, we’d love if you can pull the current master of winston-papertrail and run it. We’ll wait at least 2 weeks to see whether any issues come up from wider use of this and one other change. If you encounter problems with master which don’t occur in the current release, please open a new GitHub Issue with the transcript and reference #34.
