Unfortunately it's too late to get this fixed in RHEL 7.2, would need to wait probably for RHEL 7.3.
Comment 4 Siteshwar Vashisht 2015-12-15 06:22:25 UTC 
This bug is still reproducible if russian layout is used as primary keyboard layout. For e.g. with this xorg configuration :


Section "InputClass"
        Identifier "system-keyboard"
        MatchIsKeyboard "on"
        Option "XkbLayout" "ru,us"
        Option "XkbVariant" ","
        Option "XkbOptions" "grp:alt_shift_toggle"
EndSection

From  my understanding this bug was never fixed in Qt4, however it was fixed in Qt5 with this change request https://codereview.qt-project.org/#/c/96993/
Comment 8 Jan Grulich 2016-01-19 08:53:32 UTC 
Granting dev_ack+, patch is available.
Comment 9 Jan Grulich 2016-03-24 09:42:02 UTC 
Fixed in qt-4.8.5-12.el7.
