Comment 2 for bug 143344

ClientStorage._handle_extensions sets up method proxy objects as attributes of the ClientStorage instance. Those proxy objects hold a reference to ClientStorage._server, so ClientStorage._handle_extensions needs to be called when ClientStorage._server changes valid. It gets called from notifyConnected which (thanks to deferred cache validation) is sometimes too soon.

The low impact change is to call ClientStorage._handle_extensions at more/different places. Maybe refactor the several assignments to self._server into their own method.

Im unlikely to get round to implementation/testing of this for a while.... can anyone else pick this up?
