I'm completely lost. Where does this interactive call of
dbus-handle-event comes from? And where those strange arguments? Well,
there's a wannabe D-Bus event "(dbus-event (- arg))", but I have no
idea how it is composed.

Do you have a recipe how to provoke this error? Or could you bisect
Emacs git in order to find the change which has introduced the problem?

Best regards, Michael.
