Seems so. Launching LyX with -dbg gui gives some interesting results. For the non-crashing case (--disable-stdlib-debug): Toc: at depth 1, added item 1 Einleitung Toc: at depth 1, added item 2 Die ersten Schritte mit LyX Toc: at depth 1, added item 3 Das Schreiben von Dokumenten Toc: at depth 1, added item 4 Mathematische Ausdrücke Toc: at depth 1, added item 5 Vermischtes Toc: at depth 1, added item A Literaturverzeichnis QToc: type_ 0 toc_models_.size() 1 QToc: type_ 0 toc_models_.size() 1 QToc: type_ 0 toc_models_.size() 1 QToc: type_ 0 toc_models_.size() 1 QToc: type_ 0 toc_models_.size() 1 QToc: type_ 0 toc_models_.size() 1 form_->tocModel()->rowCount 6 form_->tocModel()->columnCount 1 And for the crashing case (stdlib-debug enabled): QToc: type_ 894323136 toc_models_.size() 0 lyx: SIGSEGV signal caught Sorry, you have found a bug in LyX. Please read the bug-reporting instructions in Help->Introduction and send us a bug report, if necessary. Thanks ! I think I don't have to stress that the value of type_ is bizarre. I have no idea where this obscure value is set. Jürgen
