It looks like Krusader does not have automatic builds available at cdn.kde.org/ci-builds. These builds are generally very helpful for testing and in my case checking translations.
Maybe some of that information can help you: I follow the steps of https://commits.kde.org/krusader?path=INSTALL in order to build and use the git version of Krusader (with its translation files). If I execute `krusader`, I see the texts in Spanish (because I'm using Kubuntu in Spanish), that produces the same effects as when I execute Krusader specifying this localization: $ echo $LANG es_ES.UTF-8 $ LC_ALL=es_ES.UTF-8 krusader If I execute `LC_ALL=C krusader`, I see the texts in English. Different aspects of localizations (like the thousand separator or decimal point character) are also changed. That way, I can perform some related tests.
