"Battery Critical" is not translated/translatable

[Albert Astals Cid]

$ grep -r "Battery Critical"
Binary file lib/arm-linux-gnueabihf/indicator-power/indicator-power-service matches

The code seems marked for translation
$ grep -r "Battery Critical"
src/notifier.c: : _("Battery Critical");

But then

$ msgunfmt /usr/share/locale-langpack/*/LC_MESSAGES/indicator-power.mo | grep Critical
$

https://translations.launchpad.net/ubuntu-rtm/14.09/+sources/indicator-power/+translations says everything is translated (39 messages)

And running make po in the sources gets you a .po with "Battery Critical" in it and 36 messages instead of 39.

So it would seem that translations.launchpad.net is outdated?
