Native alphabet group order
Gajim currently uses some weird type of group ordering (ASCII or something). It should use current locale settings. See the screenshot. I am using cs_CZ locale. Right order should be:
General, Others, Práce*, Projekty, Služby, Škola*, SMS, Ubuntu
With asterisk are marked groups which are placed incorrectly. It you have more groups, it's hard to search in them when aplhabet sorting is not really alphabet sorting.
