Couldn't create an item

[burgum]

Hello,
I've installed zabbix server using postgresql as DBserver. it's working fine, but I've got a problem, when I'm trying to create item to monitor I've got DB error

pg_query(): Query failed: ERROR: duplicate key value violates unique constraint "items_applications_1"
DETAIL: Key (applicationid, itemid)=(356, 23328) already exists. [include/db.inc.php:511]
Error in query [INSERT INTO items_applications (applicationid,itemid,itemappid) VALUES ('356','23328','5525')] [ERROR: duplicate key value violates unique constraint "items_applications_1"
DETAIL: Key (applicationid, itemid)=(356, 23328) already exists.]
SQL statement execution has failed "INSERT INTO items_applications (applicationid,itemid,itemappid) VALUES ('356','23328','5525')".

I've checked table items_applications but there is no records with that values

Which version of Zabbix you have installed? It was a setup from scratch or update?
You are trying to create item via API or web interface?

zabbix version 2.0.5, new installation from sources on Debian
trying to create item from web interface

Can you upgrade to 2.0.6 and check for this error there?

Heilig, thank you

On my second VM I installed 1.8.2 from debian repository & it works fine. So I'm using it now.
Later I will try to update my problem server from 2.0.5 to 2.0.6 and post the result.
