I forgot to say that I installed dbus, python-dbus, python2-dbus (I already had ibus and ibus-anthy) and restarted the machine, but nothing changed. I did this while "~/.bash_profile" still had this:

    export GUIX_GTK2_IM_MODULE_FILE="$HOME/.guix-profile/lib/gtk-2.0/2.10.0/immodules-gtk2.cache"
    export GUIX_GTK3_IM_MODULE_FILE="$HOME/.guix-profile/lib/gtk-3.0/3.0.0/immodules-gtk3.cache"
    export IBUS_COMPONENT_PATH="$HOME/.guix-profile/share/ibus/component"
    export GTK_IM_MODULE=ibus
    export XMODIFIERS=@im=ibus
    export QT_IM_MODULE=ibus
