I don't have german Language in Sylpheed Claws, although I choose German in GDM. Sylpheed Claws supports German and according to their FAQ, setting the language in GDM should work. (I had a german sylpheed claws in debian)
This is due to an obscure bug caused introduced when we fixed sylpheed to work alongside sylpheed-claws. It is unlikely to get fixed any time soon, as sylpheed-claws is classified as experimental anyway. If you need german locale, put a symlink from sylpheed.mo to sylpheed-claws.mo in /usr/share/locale/de/LC_MESSAGES, thus: cd /usr/share/locale/de/LC_MESSAGES ; ln -s sylpheed-claws.mo sylpheed.mo If you are feeling adventerous, you could look into how to have sylpheed-claws try to open the sylpheed-claws.mo file instead of the sylpheed.mo file, then reopen the bug.
Hello, Today is 03.02.2003 and that bug is still not fixed. The workaround with soft-linking provided here works, but it doesn't fix that bug. That would be nice if that information will be provided while installing sylpheed-claws (as better workaround -- I spend some time to realize that trick). Greetings, Luke PS. I think that no locale works on s-claws, am I right?
