Bug Description

On Ubuntu 18.04 (bionic) I am not able to use Ctrl+Shift, Control+Alt and other combinations which include only modifier keys to switch input source (works in gnome shell).

I solved this problem by making patch for gnome-flashback.
The problem with function gtk_accelerator_valid(keyval, modifiers), which always return False for such combinations. So I`ve just removed this validation.

Patch also include fix for modifier release event.

This combinations can set using gsettings(or dconf-editor) for example:
gsettings set org.gnome.desktop.wm.keybindings switch-input-source "['<Control>Shift_R']" (does not work in gnome-control-center).

My OS is:
