Description:
Looks like I'll have to use windows task manager to kill this as this error message is stuck in a loop - when I click on the "close" button, the message comes back.

How to repeat:
when I click on the "close" button, the message comes back.

Yes, this also happened to me on Windows XP just yesterday.

If this happens again, please right click in the report a bug window and select the Copy Info/Stack menu item and paste it here.

I can duplicate it all the time.  Here is the stack as requested:

One more question: can you please provide a step by step method to repeat this? It seems you can repeat it easily, while I can just get the report a bug dialog with no such loop.

I have the schema open.  I click on "Model" then "Validation" then "Validate all".  I close the output window/tab by clicking on the x.  Then I click on Model, Validation (MySql), Validate all.  That's when I get the error.

Fixed in repository.

Thanks for fixing it.  
Roman

fix confirmed in repository

Thanks - it works in 5.2.29.  YAY!

An entry has been added to the 5.2.29 changelog:

In the Model View, MySQL Workbench crashed when the Output tab was reopened after previously being closed.
