Hi Atsuyoshi,
Thanks for your work. I've tried your packaging script on Mavericks (OS X 10.9). Fix in rev15362 were also needed for Mavericks. Perhaps other versions will need the same workaround.
I've not been building on anything other than 10.7 so far so I only committed that one, but I will propagate it to the others, as they will be necessary.
In my opinion, this is a good opportunity to fix bug #476678.
Thanks for flagging this up. Reproduced it on my end.
It works fine with Koich Hyodo's fix in comment .

Confirmed. I'll commit this simple fix.
If I get time, I'll also look at su_v's other improvement (using the global "AppleLanguages" defaults value), might not have enough time to test this one properly in time for 0.92.2 though.
Cheers, Tim
