[Scribus] 1.3.3.1 GUI language problems

[Michael Engel]

Hello
I just installed 1.3.3.1 on a Japanese Win XP Pro.

During installation, I chose English as preferred language.

After installation the GUI was in Japanese. Under preferences, I chose
again English as GUI language - but Scribus didn't care about it.
Returning to the settings and again, the field was empty.
Again choosing English and OK and a restart - and welcome Japanese.

Bug or did I do something wrong ?

Cheers
Michael
