After deleting a layer in a diagram, and later clicking into the canvas I got an Exception. (Dealing with a click-handler on the Canvas) - After being tired of so many exceptions I clicked on continue, but i got another exception, this time within mdc.CanvasView.handle_mouse_move(). (See Stacktrace and screenshot)
After clicking "Continue" it the exception always happens again. The only thing left to do is clicking "Close". MySQL Workbench then asks to save the document. After clicking "Yes" it crashed and Vista displayed the "MySQL Workbench stopped working" window. :-(

After starting Workbench again, the same message box from http://bugs.mysql.com/bug.php?id=35598 is shown during load. After clicking Ok the file loaded, but the model just contains one table, allthough the other tables are still shown in the overview. (See screenshot 2)

When trying to delete the diagram, workbench stopped responding and froze. :-(

After a restart the same happened again, and I was still not able to delete the diagram. To reproduce I attachted the file.

I know that this is probably more than one bug, you are free to open more bugs and ask for more information.

How to repeat:
You should be able to reproduce at least the last two bugs when loading the file and trying to delete the diagram.

Tring to add an automatically generated diagram to that file also crashes MySQL Workbench. :-(
When manually adding an empty diagram and dragging the tables into it, I got the same bec.GRTManager.flush_timers(GRTManager* ) exception from http://bugs.mysql.com/bug.php?id=35598.
(Btw I received that exception numerous times during differing tasks)

Sadly that file seems to be really busted and I have no backup and was just writing a review of MySQL Workbench. :-(

A note has been added to the 5.0.17 changelog: 

Deleting an existing layer on a diagram and then editing other objects on the same canvas could generate a number of exceptions, and could corrupt the Workbench file.
