I have no idea; the changelog says it's been there since 1.0.0-1 in 2006, which
pre-dates my involvement. Setting the environment variable DBUS_FATAL_WARNINGS
still takes precedence.

I've been somewhat reluctant to revert it because libdbus has historically had
a lot of fatal warnings for things that are non-trivial, or even impossible,
for callers to check. dbus-glib is getting better at that, though (see
