How to repeat:
unsure how to repeat.

new EER diagram opened.  two tables added along with PKs.
relationship created between two tables.
another table added.
was attempting to add a relationship to a table that already had one relationship to another table.
after error no other operations are possible for a while.  operation then resumed without restarting application.

I am unable to repeat neither in latest version nor in 5.2.16
Is the bug easily repeatable with the instructions you gave?
If so, please provide a more detailed step-by-step recipe to get the crash.
Thank you.
