Using my Fedora hat, we got a bug report: https://bugzilla.redhat.com/show_bug.cgi?id=1575097
In this case the user (me again :-) ) has used the search and replace. At the end of document I got the standard dialog: "End of file reached while searching forward. Continue searching from the beginning?" Every time I said yes to replace I got a crash, the crash was reproducible. At the time I was pressed and so I did remember what was the document. I tried later with other documents and I can not trigger any crash. I am reporting this hoping that this is useful. Regards, -- José Abílio
