[Nut-upsuser] upssched script doesn't start on event

[Anna Skorokhodova (Yandex)]

Dear list,
Can't make upssched notify me on event occured.
OS: Debian,  2.6.26-1-amd64
Nut: 2.4.3-1.1squeeze1
UPS: Ippon Smart Winner 3000 connected via COM

On event ( plug out the cord from UPS ) upsmon detect's status change to 
OB and gives WALL and syslog notify, but no script starting. In syslog 
no errors and no upssched process occured, just upsmon.  There're no 
PIPE and LOCK file in  /var/run/nut/upssched/ created.
All files are located by package defaults.
