Better way to enumerate widget directories?

[kruncher]

Would the following be better for enumerating widget directories?

// Map where all widgets are
foreach (glob(APPPATH . 'third_party/*/widget/*') as $widget_path)
{
    $slug = basename($widget_path);

    // Set this so we know where it is later
    $this->_widget_locations[$slug] = $widget_path . '/';
}

Without this approach my custom widget package does not get detected.

Edit: Are custom widget plugins supposed to remove widgets when they are uninstalled? If so then there would need to be a way to prevent inactive extensions from being included in the above.
