2864	welcome page can't display when introducer connection has problems	warner		"While debugging some I2P-based introducer problems, IRC user ""ls"" noticed that the welcome page fails to render (i.e. displays a traceback) if the `ConnectionInfo` returned by foolscap's `Reconnector.getReconnectingInfo()` is None.

I think this can happen if there is no valid connection handler for the introducer FURL, but I need to explore some more to be sure.

In any case, this needs to be reported better, and not cause an exception.
