have a fresh 2.2.0 install, export zabbix server template, try to import it :
Row span of screen element located at X - 0 and Y - 2 is too big.
edit : actually, i might have had an older version of this template present, which would mean that it might have already had that screen with dimensions of 2x2
maybe we validate xml screen elements against screen data in the db, not xml itself. or something
