GnuCash Portable localization issue

Ahoi!

I noticed a (small) issue:
I want to use GnuCash in German, so installed the required language package and edited the "GnuCashPortableSettings.ini" as needed. But GnuCash did not start in German but in English.

I have an English Windows Vista using German as input language. Portable Apps Menu is also in English.

But if I change the language of PA Menu to German then GnuCash also starts in German even if "GnuCashPortableSettings.ini" has not been modified.

So it seems GnuCash only looks what language PA Menu has and loads the corresponding language...
