thunderbird-1.0.6_1 port problem?

[Junji Nakanishi]

Hi,

I'm using Thunderbird with ja_JP.eucJP locale on FreeBSD 5.4-STABLE.
Recently I updated the version of Thunderbird from 1.0.6 to 1.0.6_1.
And, The Japanese folder name in Inbox came to be garbled.
(both existing folder and created new folder.)

However, this problem didn't happen when Thunderbird was used with ja_JP.UTF-8
locale.
And, this problem had not occurred before.
What is the problem?

Thanks,
