The problem boils down to the fact that the paragraphs are not validated when only paragraphs are previewed. Thus, runparams.use_polyglossia is wrong in this case, leading eventually to the attempt to pop an empty stack. Another, less critical consequence is that polyglossia markup is shown in the preview where babel markup should show up. The attached patch fixes it. I'll commit to master since it seems obvious to me. Shoud also go to stable. Jürgen
