That crash file is not relevant indeed. Can you install debug symbols for libreoffice, then run libreoffice in gdb and see if you get a useful stacktrace?
See https://wiki.ubuntu.com/Debug%20Symbol%20Packages for how to install the debug packages, and then from a terminal run "gdb --args libreoffice --writer" and reproduce the crash. At the gdb prompt input "bt" to get a backtrace. ** Summary changed: - libreoffoice crashes when trying to save + libreoffice crashes when trying to save -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to libreoffice in Ubuntu. https://bugs.launchpad.net/bugs/1750087 Title: libreoffice crashes when trying to save Status in libreoffice package in Ubuntu: Incomplete Bug description: To reproduce type hello world into a libreoffice document.
