Sure. No idea where it got lost.

Yes, it is a Perl problem, sorry Bruno for addressing you. I didn't  
notice that I hadn't the package for gettext_xs installed  
(libintl-xs-perl for Ubuntu 8.04). As soon as I installed that, the  
problems disappeared - no matter whether I chose gettext_xs or  
gettext_pp in the Perl code. (Maybe I do not call the function  
select_package() well?) - However, when I deinstalled libintl-xs-perl  
and was left only with libintl-perl, the error reappeared.

I have attached a testcase, kept as simple as possible. Two perl
scripts which are different only in the textdomain used; and the two
textdomains differ only in their "Plural-Forms" line, as shown above.

This is the output on my system, when I have libintl-xs-perl NOT installed:

$ LC_MESSAGES=en_US.ISO8859-1 perl langtest.pl
Translation for number 0: Zero
Translation for number 1: One
Translation for number 10: Many, namely 10

$ LC_MESSAGES=en_US.ISO8859-1 perl langtest_wrong.pl
Translation for number 0: One
Translation for number 1: Zero
Translation for number 10: One

The untranslated strings all start with "UNTRANSLATED_", so I am sure that the
textdomains are really used, but wrongly.

Best regards,
Viktor.
