Problem translating key and_x_others

Hi,

I'm having problems translating the key and_x_others with 4.0.1 and also with 4.0.2

I translate, save and it should be done, but it is never done... anybody else?

I want to know before sending a bug to know if it is a global problem (bug) or my problem

I suppose it is this bug http://community.invisionpower.com/4bugtrack/400-duplicate-languages-key-and_x_others-r4974/ but it indicates FIXED and it continues happening to me...
