To reproduce, apply the attached patch to master and compile. Then: 1. Open lib/doc/sk/Intro.lyx 2. Preview as PDF (LuaTeX) Sometimes the above will give an error, sometimes it won't. When it is successful, the following output (added with the patch) is shown: "mit_second is not empty!" Within a given LyX session, the compile will always give an error or always not give an error (even if you force a recompile by adding text, so not using the cache). So to test multiple times, remember to exit LyX and then reopen sk/Intro.lyx. Scott
