In the Monitoring->Screens function, when you change the timeline to anything you receive the following error:

• ociexecute() [<a href='function.ociexecute'>function.ociexecute</a>]: ORA-00936: missing expression[/var/www/html/include/db.inc.php:502]
• SQL error [ORA-00936: missing expression] in [INSERT INTO profiles (profileid, userid, idx, value_int, type, idx2) VALUES (42, 1, 'web.screens.period', 3600, 2, )]
• ociexecute() [<a href='function.ociexecute'>function.ociexecute</a>]: ORA-00936: missing expression[/var/www/html/include/db.inc.php:502]
• SQL error [ORA-00936: missing expression] in [INSERT INTO profiles (profileid, userid, idx, value_str, type, idx2) VALUES (43, 1, 'web.screens.stime', '201004252300', 3, )]

I am able to replicate this with a blank Zabbix install.
