Description:
Signed with OpenPGP signature ODT document doesn't show in its properties as "signed". In one case, LOffice breaks exactly after entering to menu "File->Properties", another case - breaks after closing the signed file.
So, crash analyzer gives an output:

Application: soffice (soffice), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
To enable execution of this file add
	add-auto-load-safe-path /opt/libreoffice6.3/program/libpython3.5m.so.1.0-gdb.py
line to your configuration file "/home/dodo/.gdbinit".
To completely disable this security protection add
	set auto-load safe-path /
line to your configuration file "/home/dodo/.gdbinit".
For more information about this security protection see the
"Auto-loading safe path" section in the GDB manual.  E.g., run from the shell:
	info "(gdb)Auto-loading safe path"
