Hi Wolfgang, thats a little bit difficult, because the error apparently happens at a random position in the document (you can add a syntax error in the document an change the position of the syntax error in the document until lmtx crashes before it detects the error to get the paragraph where the crash happens, but that paragraph is fine). And I don't know why the error happens in one document and not in others (I use similar commands in affected and not-affected documents; the affected documents are long but not the longest documents I have) or why it happened two days ago in one document, which is fine today, and today at another document (which was fine two days ago). So I don't have a clue how to reproduce the error.
