FWIW I have the following in my ~/.bash_profile.  If you search the
email list archives for these environment variables, you'll find some
relevant discussions:

# Enable GTK+2 and GTK+3 programs to simultaneously use the right
# immodules cache file.  This is a Guix-specific work-around.
# See: https://lists.gnu.org/archive/html/guix-devel/2016-08/msg01634.html
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"
--8<---------------cut here---------------end--------------->8---
