sendmany not working again

The sendmany command isn't working.  I'm guessing there's an error in my input because it gives me HTML error 500.
Here's the array I'm passing:

array
  '123rCgeKEsEg55DQtwbH5KFEk1NTVAvwuL' => float 0.0252864
  '17hvJGppNaXimMhf68tTogxoDAJERUCwnB' => float 0.0695376
  '1DMNXygHSc7GvEZHweNsTQv5TMDS9kAUrz' => float 0.362844
  '1Aq797j4xZmFb2ddnTwXaSD2JMQo1nmDJ9' => float 0.0250416
  '17t1A9j8db3KyYmShNpchbcoRgPimmYQ1J' => float 0.0423216
  '16tFBmSGyGNfcuXkPn4Ckfkd2YZz7y3Ypq' => float 0.3660624

Anyone see anything wrong with it?

Bump, anyone?

That doesn't look like JSON. {"address": 1000, "address2": 500, "address3": 700}
