pppd doesn't play well with NetworkManager while establishing DSL connection

Binary package hint: ppp

As it was reported in bug 432205 and its duplicates, NetworkManager presently is unable to establish a DSL connection in Ubuntu 9.10 rc. In logs provided by several users, this line

NetworkManager: <WARN> pppd_timed_out(): Looks like pppd didn't initialize our dbus module

looks very suspiciously, and probably ppp maintainers could help make establishing DSL connections from NetworkManager possible again.
