Zabbix frontend fails on IPMI sensors with trailing spaces

Zabbix frontend should not sanitize the input on IPMI sensor field as sensor names can contain trailing spaces.

Here at UNAM we have a cluster with HP ProLiant DL145 G2 computing nodes that support IPMI via iLO, the problem is that among the 22 sensors it has, two of them have names with trailing spaces (i.e. "VBAT " and "VCC5V ") which zabbix is able to monitor only if I manually change the "ipmi_sensor" column from table "items" in my database.

So the problem is that I'm unable to define the items to monitor for this IPMI sensors via GUI, be it manually adding sensor information or exporting to xml -> modifying sensor name in xml file -> importing from xml.

Thanks,
Yuri.
