Problems with decimal point (gnucash 1.4.8, LANG=de_CH)

[Niklaus Giger]

I start using gnucash for my personal accounting this year.

Now it bothers me (I didn't notice it when I tested gnucash last July) that 
"." is used as a thousand separator instead of the decimal point.

My environment is as follows:
Debian (+/- unstable)
KDE2 as GUI
gnucash 1.4.8
I have enter manually in my shell "export LANG=de_CH; export LANGUAGE=de" 
before starting gnucash in order to make gnucash recognize my preferred 
language.

Is there a problem with my setup or with gnucash? 

Any hints are appreciated.

Regards
