I have wp_content_url set to help speed up load times by moving static content off to static.hostname.org.
It seems wp_plugin_url is normally based off wp_content_url, but you can set to to be something normal, like http://www.hostname.org. It seems link library doesn't support having wp_plugin_url set. The main symptom of this is the icon for the settings page doesn't load, it just shows as a question mark, and the url points to static.hostname.org/wp-content/plugins/...
Any chance we can get this fixed? =)
