The bad news is that my gnus persist in saying to me that there is no /tmp/ltxpng/image.png ... here is the message : Loading reftex...done Loading reftex...done Creating LaTeX Image... Failed to create dvi file from /tmp/orgtex6500qb1.tex Ispell process killed Starting new Ispell process [aspell::fr] ... Mark set Sending... Mark set [2 times] mm-insert-file-contents: Opening input file: aucun fichier ou dossier de ce type, /tmp/ltxpng/latex6500dRv_882193079df36c558aa30f292b503a46cfd2aa88.png Auto-saving...
