error: The "profiler" extension is not enabled in "@WebProfiler/Collector/request.html.twig" at line 77. 

Click any section on Symfony debug bar to activate profiler. On profiler page click on ```View last 10``` then any token link. It will shows up error message as above. 
I think this isn't bolt issue but Silex. I think ```...\Twig\WebProfilerExtension``` should be added in ```\Silex\Provider\TwigServiceProvider``` but it is missing. 
I couldn't find a better place than in ```Application.php:206```...
