Deleting more then 900 objects results to wrong SQL

Hi,

I make a fresh installation of Zabbix 1.6.2 with the good php frontends. I have 3000 hosts monitored.

I would try to delete all the hosts, but I could'nt. I receive a message error as in attachment file. Sorry to not add the error in the message, but they are more 32'000 characters in the error.

If I make the same, but for 200-300 hosts, I could delete these hosts...

Before, in Zabbix 1.6.1, the same operations works great.
