When exit from the stored procedure editor, randomly Workbench display the message "Object reference not set to an instance of an object"

// How to repeat

- Goto Stored Procedure explorer
- Open an existing SP (Right click and ALTER Stored Procedure..)
- Add few dots to the SP documentation
- Click Apply 
- Close the SP editor
Above steps would trigger "Object reference not set to an instance of an object."

I have the same problem on Windows 7 Service Pack 1.

Fixed as of the upcoming MySQL Workbench 6.1.6 release, and here's the changelog entry:

Closing the "Stored Procedure Editor" after changing a stored procedure
(and clicking "Apply") would emit an "Object reference not set to an
instance of an object." error.

Thank you for the bug report.
