I am happy to inform you that we have recently landed Bug 903433, which ensures that uncaught errors or rejections in Promise.jsm or Task.jsm are now displayed.
So, from now on, if you are attempting to debug asynchronous code using Promise.jsm/Task.jsm, don't forget to look in the browser console output, you should find the error that you are looking for. Additionally, since bug 908955 landed, Promise.jsm/Task.jsm will dump() any programming error (e.g. TypeError, SyntaxError and the ilk) immediately, regardless of whether it is caught. So, keep an eye on your stderr, too. Both changes should make debugging async code much easier.
