Under plain openbox in pclos, this gives an error message about not finding moderators. Then it never shows any sellers. Also, it has been showing this for about 15 minutes:

Shutting down the built-in server
The built-in server is being shut down. This may take up to a few minutes. During shutdown, important cleanup tasks are done. It is important not to interrupt this process. When the process completes, the app will close.

Is there a gnu/linux this is known to work in? I'd install another system if there is.
