I couldn't repeat on Windows Vista Home Premium X64.

I can not repeat it on Windows server 2008 too.

I can not repeat this on XP SP3 also. Please, send the results from Help > System Info menu item and initial .mwb file to open, if possible.

Original mwb to be used in the test scenario.

I am also not able to repeat this.

What server version are you using?
Do you use remote or local server?
Which sql-mode are you using?

The computer in question has 6.0-alpha installed, but the MySQL service is not currently running.  Therefore there is no active connection.

The Workbench modeling tool is being used to document a data model, not to forward engineer into any MySQL database.  The exception is thrown during updating the ER diagram, and no attempt is made to synchronize to MySQL.

I would say that the exception only occurs when it would cause the maximum amount of damage or inconvenience; for example, after heavily rearranging the diagram, recreating foreign key references, importing new tables, renaming or re-data-typing many columns.

However, it must also be noted that the unknown exception appears to occur in a parallel thread or process, which does not always prevent saving the mwb file.

As I say, if the exception dialog could offer up a comment as to which exception is thrown, we might be able to help each other.

Still I am not able to repeat.

Dave, when you get the error dialog you can right click on a free place on it which will bring up a context menu. This will allow you to copy the stack trace to the clipboard. Please add that to this report. 

Additionally, since we cannot reproduce the problem here, can you try to create a list of minimal steps to make the issue show up? Otherwise we might not be able to fix it.

Thank you.
