Hi all, Though the bug is closed, I still faced this issue. Solution was to explicitly install gtk+ along with libreoffice (ie. specify it in the 'packages' field of my home-environment declaration, in my case).
I'm not sure if this is expected or if there's any way to fix it. Just wanted to share how I got it to work. I should note that in order to run libreoffice even in a `guix shell`, you need to specify gtk+, as well as coreutils and sed (for the /bin/libreoffice startup script, I think) - guix shell --pure coreutils sed libreoffice -- libreoffice
