This patch fix the correct behavior for address_type method in application_helper.rb, where the mac address was uncorrectly associated to :vnc instead to be a mac symbol.
<public_addresses>
<address type="vnc">00:50:56:a9:00:05</address>
</public_addresses>
JSON Format:
"public_addresses":[{"address":{"type":"vnc","value":"00:50:56:a9:00:05"}}]
