TorBirdy 0.1.2 uses wrong locale

Using Thunderbird 31.2.0, LinuxMint 17.

My locale (LANG) is set to ja_JP.UTF-8, and I also have the English (US) localization packages installed through the packet manager.

Problem: TorBirdy is in Arabic.

Expected behaviour: TorBirdy is in Japanese (my default locale) or English.
