I found a way to reproduce it: 1) Open a document with info inset included. 2) Go to a line with info inset to display (some text to scroll down). 3) Position the cursor near the inset. 4) Quit LyX and restart. 5) Load the previously closed document -> crash on cursor positioning. To solve that issue one has to remove the offending line in section [cursor positions] of the session state. After the removal I can reproduce it again with the same document and the same procedure. I'll attach my example document. To trigger the crash the info inset has to be visible and it must be some scroll down involved to show the cursor position on startup. Stephan
