Description:
Unknown exception caught in "Canvas.h Line 146"
When trying to delete a foreign key.  Happens both when I delete the column, or when I delete the link and say "yes" to deleting the associated column.

Then when I try to move the table, I get:
System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
   at mdc.CanvasView.handle_mouse_move(CanvasView* , Int32 , Int32 , EventState )

How to repeat:
Two tables, create a foreign key (I use InnoDB) and then try to delete it.

Thank you for the bug report. Duplicate of http://bugs.mysql.com/bug.php?id=34816.
