That's this changeset from Mozilla Central: https://tbpl.mozilla.org/?rev=3328dfb0d932

The error message in comment 2 is from: http://mxr.mozilla.org/mozilla-central/source/netwerk/protocol/app/AppProtocolHandler.cpp#372

And so, my guess is Marco's patches were messing with what I believe to be appinfo objects, so maybe those patches are at fault?
* https://hg.mozilla.org/mozilla-central/rev/dbd05d2e58a5
* https://hg.mozilla.org/mozilla-central/rev/96eaa0f376ab

That's not much of an analysis, and I may be wrong, Marco what do you think?

Fabrice I think we suspecting that https://hg.mozilla.org/mozilla-central/rev/96eaa0f376ab caused this. He is verifying a backout right now.

Yep, that's the offending one. I'm backing it out.

Fixed via backout in bug 961282.

Did this problem happen only if you reset B2G? If that's the case, I think I know what's the issue in my patch (but I can't test at the moment because I don't have a b2g device).
