I tried to make L10n repacks work fine with omni.jar and I mostly have succeeded, but what I didn't look at is repeated L10n repacks for different locales from the same directory structure, which is what our buildbots do. There seems to be a small glitch (missed porting from l10n.mk) that makes those fail.
I *should* have a patch for that, but I'm trying to confirm on a slave right now.

port missed hunk
This ports the missing l10n.mk hunk from http://hg.mozilla.org/mozilla-central/rev/d37b6b337227 to suite/ as we're not using l10n.mk yet. I tested that it works on a slave with the steps our factories are applying.
Thanks for the fast review, pushed as http://hg.mozilla.org/comm-central/rev/1025dd5f0c49
