All "state" stats are marked as "other"

Hi, I'm not using your script but made a collectd plugin using your code (thanks! )
I modified the line
  state = row.get('state')
for
  state = row.get('State')

I don't know if this issue is related to the MySQL version we are using or if it is a bug, that's why I'm posting this issue. ;)
