Bug #44340 Deleting/cutting relation from diagram crashes MySQL Workbench

Description:
Deleting or cutting a relation from a diagram often crashes MySQL Workbench.

How to repeat:
See model:
http://925.dk/public/mbb.mwb

Go to the diagram and either:

1) Cut the "vi_phone_no" relation.
or
2) Delete the "vi_phone_no" relation (but keep in model).

- and woila crash.

Thank you for the problem report. Do you get the crash every time you delete one of the relationships? What version of Mac OS X do you use? 

In my case Cut is disabled, by the way, and I was able to get a crash after delete and some other manipulations only once on 10.5.6.

Yes, each time I delete/cut the "vi_phone_no" relation it crashes.
Using MAC OS X 10.5.6.

I right click the relation, and select delete or cut. And they are not grayed out (and why would they be).

I use the Workbench version that is available from here http://dev.mysql.com/downloads/workbench/5.1.html as Mac OS X 10.5 Intel (DMG) 5.1.10a.

I've got a repeatable crash at least after double-clicking one of the relationships to view/edit it more than once. We definitely have a problem here.

This seems fixed (or not an issue) in the latest beta version.

Cut is properly disabled now (theres no cut/copy/pasting of relations).
deleting the FKs doesnt crash WB.

An entry was added to the 5.1.13 changelog:

Deleting or cutting a Relation from an EER diagram crashed MySQL Workbench.
