Laravel 5.2 Route not working ERR_EMPTY_RESPONSE - php

Question

When calling a resource route, the server dies. Resulting in GET http://localhost:8000/tag net::ERR_EMPTY_RESPONSE.
Serving via php artisan serve on localhost:8000 on a *nix box. Same results for ff and Chrome.
Ajax used is $.get
Routes:
Route::group(['middleware' => 'auth'], function(){
Route::resource('business', 'BusinessesController');
Route::resource('business.show', 'BusinessesController');
Route::resource('business.create', 'BusinessesController');
Route::resource('business.update', 'BusinessesController');
Route::get('order', ['as' => 'order.default', 'uses' => 'BusinessesController#create']);
Route::post('order', ['as' => 'order.post', 'uses' => 'BusinessesController#signUp']);
Route::resource('tag', 'TagController');
});
Route::auth();
All routes work, with the exception of 'tag.' Moreover, running php artisan route:list results in a segmentation fault.
The following works:
Route::get('tag', function(){
$tags = App\Tag::get()->toArray();
return $tags;
});
The controller:
<?php
namespace App\Http\Controllers;
use App\Http\Middleware\TagService;
use Illuminate\Http\Request;
use App\Http\Requests;
class TagController extends Controller
{
private $_ts;
public function __construct(TagService $tagService)
{
$this->_ts = $tagService;
}
/**
* Display a listing of the resource.
*
* #return \Illuminate\Http\Response
*/
public function index()
{
dd('test');
return $this->_ts->get();
}
/**
* Show the form for creating a new resource.
*
* #return \Illuminate\Http\Response
*/
public function create()
{
}
/**
* Store a newly created resource in storage.
*
* #param \Illuminate\Http\Request $request
* #return \Illuminate\Http\Response
*/
public function store(Request $request)
{
dd($request->all());
}
/**
* Display the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function show($id)
{
//
}
/**
* Show the form for editing the specified resource.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function edit($id)
{
//
}
/**
* Update the specified resource in storage.
*
* #param \Illuminate\Http\Request $request
* #param int $id
* #return \Illuminate\Http\Response
*/
public function update(Request $request, $id)
{
//
}
/**
* Remove the specified resource from storage.
*
* #param int $id
* #return \Illuminate\Http\Response
*/
public function destroy($id)
{
//
}
}
The request doesn't seem to make it to the controller.
