[opensuse-factory] Language files to a package not found

Hi, maybe one of you has an idea....one package I'm building includes the *.po* files for language dependent elements. Up to now it was using *.mo files, which were detected by the %find_lang %{name} %{?no_lang_C} Macro in the spec file. Of course now the *po files are build but unpacked, resulting in an error. Is there a way to find the *po files with the %find_lang macro as well? Or do I have to include them manually (as I currently do)? Thx Axel
