I don't think this is a bug; at least, upstream don't consider it to be.
Their policy is that the documentation guarantees only apply when
the function is used correctly, and that invalid arguments that trip
a g_return_if_fail check are considered to be incorrect use, which
causes undefined behaviour.
I've asked to make this clearer:

If you're calling a function in GLib that takes an object-path argument,
upstream's policy is that you are responsible for ensuring that it is
actually a syntactically valid object-path. In this case the problem is
"=", which isn't allowed - see the D-Bus Specification for details.
