Created attachment 114422 [details] Screen capture from KDE control center demonstrating the problem
It looks like some problem in Bugzilla wiped out the content of the original report. Anyway, in the attached screen capture you can see lots of ',' characters instead of 'ä' characters that should be there. Other KDE programs have similar errors as well.
This bug hasn't been fixed in FC4 final.
Updated to kde-i18n-Finnish-3.4.1-0.fc4.1, no improvement.
it seems a bug in kde-i18n upstream and should be fixed in new upstream. Could you please report this problem to http://bugs.kde.org/. thanks
Upstream report exists already: http://bugs.kde.org/show_bug.cgi?id=106866
