The statusbarpanel doesn't implement nsIAccessibleProvider but the statusbarpanel-iconic version does. The normal statusbarpanel should also implement it yet use nsIAccessibleProvider::NoAccessible (or something else if more suitable) so that the element always implements the same interfaces.
Created attachment 306200 [details] [diff] [review] patch statusbarpanels is much similar with xul:buttons or xul:toolbarbuttons, so let's expose it like them.
