Here are mine: Installed versions: 4.28(23:40:35 09.10.2009)(X pcf psf ru-dv ru-g ru-i -a-like-o -bolddiag -quote -raw-font-data -ru-k -width)
But I think USE-flags aren't connected with this strange behaviour. I already said, that russian letters are not displayed in every font, including misc-fixed, for example. I also tried original (from official site) fonts, but the result was the same. Definitely fonts are not the reason.
