If a tab is rendered inline make a simple check and show a message to user if tab can not be rendered.
This is especially nasty when for example user tries to open a tab, it fails (then tabs' Id cookie is saved in user browser). Next page view will brake whole ERP5 front page (then this failing tab is loaded inlined).
