After Bug 1002545 landed [1], the building process gets stuck when I try to run "DEBUG=1 make". Please refer to the attachment for the logs. [1] https://github.com/mozilla-b2g/gaia/commit/529298abcf6eec7788dcab6d9932824e8bf4ad68

As Alexandre mentioned on https://bugzilla.mozilla.org/show_bug.cgi?id=1002545#c91. It seems a problem in download.jsm. We could replace it by old one to solve this problem. Maybe Alexandre could help with us replace Downloads.jsm usage with saveURI.

Another question is I still have no idea why the download.jsm caused failures on ubuntu12.04 but passed on ubuntu14.04.

I just tested download additional extensions and it seems to work just fine. Ricky, could you test this patch against svoperapps? It is also using download-manager and I would like to ensure it also keep working fine. I'm wondering if the usage of Downloads.jsm relates to the various exceptions about nsHandlerService.js:120 we can see when building gaia, as well as the intermittent stack reported in bug 1070622. If that's the case that would be a great win!

Nice! Luke, do you want to give it a try on your ubuntu12.04?

Cool! That patch works. Thanks a lot.
