network-manager: can't connect using PPPoE

Binary package hint: network-manager

This is 9.10 beta with updates.
I had to use pppoeconf on the command-line to connect to internet because network-manager can't connect.
With 9.10 beta i couldn't connect due to a strange error message from network-manager.
i ran pppoeconf and connected, upgraded, the error message is gone. so a problem less.
then i tried to remove all the files that pppoeconf created to get a clean environment. I think I did it.

then configured network-manager again, but it still can't connect.
all is going OK until the point where it should actually connect and that fails, it just says it can't connect, no error message.

in syslog is written:

-------------------

i tried to start the pppd command-line listed in this log by hand, and i get (interesting part only):
