JSON response for missing exec simulation differs between persisting and explicitly specified

[MSLaguana]

When testing the behavior of cordova.exec when there is no pre-defined plugin simulation, I saw this:

>cordova.exec(suc, fai, "fooService", "bar", [1])
undefined
fail
{}
>cordova.exec(suc, fai, "fooService", "bar", [1])
undefined
fail
{"0":""}

The first time it popped up the "Please specify a response" dialog, and I left the field empty and clicked fail, but also told it to persist the result. The first response was just {} as expected, an empty object, but the second time when it used the persisted result the response had a 0 property.

Can you reproduce the bug?
