From what I could tell, it has to do with trying to traverse the themes folder during service registration when that folder hasn't yet been created. Changing the singleton registration to the following apparently fixes the issue:

$this->app->singleton('caffeinated.themes', function($app) {
    $themes = [];
    $items  = [];

    if ($path = config('themes.paths.absolute')) {
        if (file_exists($path) && is_dir($path)) {
            $themes = $this->app['files']->directories($path);
        }
    }

    foreach ($themes as $theme) {
        $manifest = new Manifest($theme.'/theme.json');
        $items[] = $manifest;
    }

    return new Theme($items);
});
