This is my last resort!!! I'm completely mad with the following problem:
All GTK applications (Firefox, Eclipse etc.) mess-up shortcuts while in non-latin layout. When in 'en' i receive, CTRL+latin_letter, and when in 'ru' i receive CTRL+russian_letter !!!! This way CTRL+C/V/X are working only for latin layouts! For me this makes those application barely usable... This is reproducible in any distro in any version.
