Zabbix server crash with dependent item

Hi,

during my tests on dependent items i encountered a crash on Zabbix server. Following are details of master/dependent items:

• Master: Log type
• Dependent: Text type, preprocessing Trim > [a-z]

Whenever i add a new line like Line1: Service MySQL was fucked the Zabbix server crashes (sorry for the language, i could have changed the bad words but it's just to give you the exact line added to log file).

You can find zabbix_server.log attached
