[Bug 334122] Re: Mobile broadband connections fail to connect

network-manager-0.8~a~git.20091013t193206.679d548

did not work for me i got:

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

i also saw no logs from pppd.

to see what happens i tried to get an strace output with

while :; do sleep .2; if pgrep pppd; then strace -s1000 -f -p $(pgrep
pppd); fi;done

write(1, "Plugin /usr/lib/pppd/2.4.4/nm-pppd-plugin.so loaded.", 52) = ? ERESTARTSYS (To be restarted)
--- SIGTTOU (Stopped (tty output)) @ 0 (0) ---
--- SIGTTOU (Stopped (tty output)) @ 0 (0) ---

This means that pppd writes to stdout, but networkmanager did not read
anything.

With this patch my huawai E220 is working now

Well it would be better to read from stdout / stderr and log it,
