Gaia: 2 new strings landed on 2.1

[Francesco Lodolo [:flod]]

Hi,
just a quick heads-up: unfortunately string freeze was broken on Gaia 2.1
http://hg.mozilla.org/releases/gaia-l10n/v2_1/en-US/rev/7c0e1c767658

When an application tries to access phone's camera and it's already in
use, we failed without warnings.
These strings already landed on Master, and they were considered a
blocker by partners on 2.1, so they got past string freeze limitations.

CCing also Dwayne to make sure that Pootle is aware of the change.

One more note on this landing for master
https://hg.mozilla.org/gaia-l10n/en-US/rev/d30dc5a64a67

As you can notice two strings were changed without a new ID. These
strings are not commonly visible to users, and the zero case is never
used. That's why we don't plan to request new IDs. Just pointing it out
in case you want to update your localization accordingly.
