Sendmany strips amounts from array

[flound1129]

I've spent several hours now trying to get sendmany working . I finally appear to have everything in the correct format, however for some reason sendmany appears to be stripping the amounts from the array I pass it.

Here's what var_dump tells me it's passing to sendmany:

array(2) {
  ["AcRHK6pzn2iT7e4xTZzYQDEitjXN3ecLaj"]=>
  float(0.06643307)
  ["Ae2ZwXUFyymNo3JVkKAjT9k3akURK7bmxo"]=>
  float(6.630817816701)
}

However when I run a tcpdump on the daemon I see the following:

"method": "sendmany",
"params": [ 
  "default",
  {"AcRHK6pzn2iT7e4xTZzYQDEitjXN3ecLaj":"","Ae2ZwXUFyymNo3JVkKAjT9k3akURK7bmxo":""},
  1
],
"id": null
}
