I'm getting lots of this in server log after upgrade to 1.8.2 (from 1.8.1):

2545:20100401:205344.883 Item [server02:net.if.in[eth0,bytes]] error: Type of received value [1264329667796] is not s
uitable for value type [Numeric (float)]

This problem is affecting my own items but also zabbix original items (as you can see above, it's net.if.in). Everything was working fine in 1.8.1 and before. Items are marked as 'not supported'.
