Comment 15 for bug 410254

I don't think "we don't support indicator applet in a vertical panel" is a satisfactory response to this. Currently, you can add an indicator applet to a vertical panel and get something that looks at first like it is working, but which doesn't actually function. If you aren't going to fix this bug properly, you need to at least check whether the applet is being added to a vertical panel, and handle the situation in some kind of graceful way, perhaps by informing the user that the applet does not work on vertical panels and then quiting.
