When I launch the version 6.1.1 application in a text terminal in the zh_TW locale the following error is emitted:

22:10:56.630: Error: Uncaught exception in thread [AWT-EventQueue-0] (LOG_ERROR_UNCAUGHT_EXCEPTION)

the application still launches properly, except from no "tip of the day" window popped up.

When I set the LANG environment variable to en_US.UTF-8 this issue is not reproduced.
