Fresh Install of enviroment: Zabbix 2.0.4
Update to 2.0.5 and the hosts lists fail with a "invalid" hosts without name and many error messages on end of page.
In the same zabbix server I put the frontend 2.0.4 back (in paralel... in new path) and the problem not apear on Zabbix 2.0.4 frontend, only on 2.0.5.
I add to this bug report the debug information and the source of pages in 2.0.4 and 2.0.5 (the both pages opening the same database).
