1083318 - PromiseWorker.js double wrapping on throw

Status: UNCONFIRMED

(Toolkit :: Async Tooling, defect)

Description

[noitidart]

User Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0
Build ID: 20141007073543

Steps to reproduce:

I used PromiseWorker.jsm and PromiseWorker.js

This example is for Windows.

The function creates a MsgBox. If you click "yes" then the promise is resolved. If you click "no" then the promise is rejected by `throw new Error('reject promise')`. And the aReason is logged. We see when rejected this is logged:

See the Error: Error:

Seems double wrapped. But we can read aReason.message, that object isnt double wrapped.

I'm not sure if this is a bug or not.
