Does it happend with the ones made from notify-send?

Anyhow, nothing allows you to work-around the bug by putting reason
&optional. Anybody can emit a wrong formatted signal on the dbus, even
with dbus-send. Based on that, any D-Bus bad formatted signal/method
call will raise an error.

Bad that's like calling a Lisp function with requires 2 arguments with
only 1. It raises an error because you call it badly. I don't see why we
wouldn't do the thing even if the function is called via D-Bus.

But yes if, you don't want to know about bugged implementation, you use
&optional in every dbus signal/method function you will use (even
outside notifications.el).
