ktalkd doesn't show ktalkdlg

[Vladimir Wiedermann <wiedermann@sturak.sk>]

Propably since last update of kde (3.1.2) on debian sid, my ktalkd doesn't
work anymore. After each talk I immediately get only message, that 
user is not logged in.
I also don't receive a mail, that somebody tried to talk me.

I tried reconfiguring ktalkd, but it didn't help me.

wido@wido:~$ ps aux | grep inet
root      2968  0.0  0.3  1860  828 ?        S    13:49   0:00
/usr/sbin/xinetd -reuse -pidfile /var/run/xinetd.pid

/var/log/daemon.log
May 31 14:02:34 wido ktalkd[3070]: connect from ...
May 31 14:02:38 wido ktalkd[3071]: cat '/tmp//ktalkdOCdTlH' |
/usr/bin/sendmail 'wido' : Invalid argument

I have exim installed, so there is problably problem with
settings, because of
/et/kde3/ktaldrc
MailProg=$KDEBINDIR/sendmail  is /usr/bin/sendmail
and I need /usr/sbin/sendmail ..

But I didn't find out, why talkd doesn't show me ktalkdlg ..
Any idea?
