Comment 1 for bug 309844

It can be fixed quit easily by changing /usr/share/X11/xkb/symbols/ru file. In the phonetics section a line

    key <AE11> { [ minus, underscore ] };

need to be added and lines like

    key <LatQ> { [ Cyrillic_ya, Cyrillic_YA ] };

should be changed to

    key <AD01> { [ Cyrillic_ya, Cyrillic_YA ] };

Corrected file is attached, hope it will be used in future releases.
