Comment 14 for bug 564034

This patch fixes a few different things, firstly menu was being called with add, which just isn't proper so this has been replaced with append. Also, the items *MUST* be shown before they are added or else the signal gets lost. This is really not ideal but it works for now, and doesn't do any harm, easy to get stung with this bug.

Some investigation into the app indicator python bindings required in order to discover the root cause of this issue.
