First of all I have last stable amule: * net-p2p/amule Latest version available: 2.1.2 Latest version installed: 2.1.2 Size of files: 3,164 kB Homepage: http://www.amule.org/ Description: aMule, the all-platform eMule p2p client License: GPL-2 And this is a very minor bug. When you set your system to other language than english, you should have amule installed in that language. If you change the language (in my case, it didn't set by itself to my own language) to other (for example english), after a restart you have it in english, but when trying to set again in the local language (in my case spanish), you realize that, despite program is now in english, in settings window, it has "spanish" option selected for language, so it is impossible to set spanish language again. You can see in config that the locale it selected (I have not compiled this locale in glibc) is bg_BG. Workarround: if have the locale for amule improperly or can't change again to your language, just edit file ~/aMule/amule.conf and set change line wich has Language=bg_BG to Language=es_ES (or your locale).
I don't use amule anymore, so I couldn't post anything. And this bug is very old. Do whatever you think is most correct (closing it, marking as invalid, etc..) because I am not able to post more information about this,
I change bug status because of comment #1
