On the group list ("Communicate" > "Contacts" > "Groups"), there is a special entry "none" to represent "none of the groups". This particular English word appears here regardless of the user's UI language selection.
This "none" should appear as an appropriate translated word of the user's UI language.
This behaviour is not by a simple "forgot to translate" mistake. It is caused by the fact that the current viewer program has a hard-coded string "none" in its C++ source file (at line 469 in "indra/linden/llfloatergroups.cpp" in case of 1.20.2.85278) and use it always, ignoring the UI language. Hence, it is impossible to fix this issue by editing XUI files only. The fix is, however, obvious. This particular string "none" should be placed in an XUI file (panel_groups.xml, probably), and the viewer program should read that string from one of the translated versions of the XUI files.
I will provide a patch to fix this issue on the next weekend (3-4 May), if nobody supplied one before then. (I'm sorry to write in this circuitous way; I'm somewhat busy recently and have no time to work on it in April...)

The word "none" on a group list appears as the English word "none" and it is unable to translate it through XUI files
The change requires translations of a text "none" into various languages. I included Japanese (ja), Korean (ko), and German (de) translations as well as English (en-us) version of XUI files. I used the following words: "グループなし" for Japanese, "그룹 없음" for Korean, and "keine" for German. (Japanese and Korean languages have no word that correspond to English "none", so I used words corresponding to "no group" here.) Other languages, i.e., Spanish (es), French (fr), Portuguese (pt), and Chinese (zh) are out of my translation skill and left untranslated.
