i exported a template from 1.6.x and tried to import to 1.8 and 1.8.1. both failed with

• Incorrect key format 'key_name[param1,param2,...]'
• Internal zabbix error
• An item key must be used in trigger expression
• Unknown ZABBIX internal error

i have other issues, like trigger dependencies being broken on import, those give an error and the process continues. this error breaks the whole import, and its not even giving a linenumber or so to debug.

example tamplate attached.
