Created Unassigned: Crashes on run if 'less-middleware' added [975]

VS crashes on Run of Node.js app with this code inn app.js

```
var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var http = require('http');
var path = require('path');
var lessMiddleware = require('less-middleware');

var app = express();

// all environments
app.set('port', process.env.PORT || 3000);
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'jade');
app.use(express.favicon());
app.use(express.logger('dev'));
app.use(express.json());
app.use(express.urlencoded());
app.use(express.methodOverride());
app.use(app.router);
app.use(lessMiddleware(path.join(__dirname, '/public')));
app.use(express.static(path.join(__dirname, '/public')));

// development only
if ('development' == app.get('env')) {
app.use(express.errorHandler());
}

app.get('/', routes.index);
app.get('/users', user.list);

http.createServer(app).listen(app.get('port'), function(){
console.log('Express server listening on port ' + app.get('port'));
});

```
Package less-middleware is installed via npm.

Getting rid of this line: 'var lessMiddleware = require('less-middleware');' fixes the crash.
