Description:
Workbench crashes after right-clicking on a table schema and choosing "Copy SQL to Clipboard".
However the problem does not always arise and sometimes performing that operation works.

How to repeat:
- Open a databse diagram
- Right click on a table schema
- Choose "Copy SQL to Clipboard"

When you'll get this crash again, please, right click somewhere in the error dialog box with no text and use Copy stack trace to clipboard context menu item. Send stack trace to this report.

I was not able to repeat this with any of my schemata.

I have to add some details. The error seems to be catched. When it happens a "MySQL Workbench Unexpected Error" message appears (this message says that the clipboard operation failed) and I can only choose to close the message (and after this workbench seems to continue to operate) or report the bug.

However, if I close and restart workbench, immediatly another 'catched' error appears (which essentially claims that Invoke or BeginIvoke cannot be called on a control if a window handle has not been not created yet. Trying to copy the stack trace causes another error) and next an access violation arises (EventType : clr20r3     P1 : mysqlworkbench.exe     P2 : 5.2.31.7110     
P3 : 4cfee506     P4 : system.windows.forms     P5 : 2.0.0.0     P6 : 4889dee7
P7 : 1521     P8 : 17     P9 : system.invalidoperationexception).

I have to run workbench again and opening the last diagram it says that it was not properly closed and allows me to recover.

This is the stack trace when the original clipboard error arises ('Operazione richiesta sugli Appunti non riuscita' could be traslated as 'Requested clipboard operation failed'):

Exception = System.Runtime.InteropServices.ExternalException
Message = Operazione richiesta sugli Appunti non riuscita.
FullText = System.Runtime.InteropServices.ExternalException: Operazione richiesta sugli Appunti non riuscita.
   in System.Windows.Forms.Clipboard.ThrowIfFailed(Int32 hr)
   in System.Windows.Forms.Clipboard.SetDataObject(Object data, Boolean copy, Int32 retryTimes, Int32 retryDelay)
   in System.Windows.Forms.Clipboard.SetText(String text, TextDataFormat format)
   in System.Windows.Forms.Clipboard.SetText(String text)
   in MySQL.Forms.UtilitiesImpl.set_clipboard_text(basic_string<char\,std::char_traits<char>\,std::allocator<char> >* content)
   in MySQL.MCallback1<void\,std::basic_string<char\,std::char_traits<char>\,std::allocator<char> > const \&>.cpp_callback(basic_string<char\,std::char_traits<char>\,std::allocator<char> >* arg1)
   in wb.WBContext.flush_idle_tasks(WBContext* )
   in MySQL.Workbench.WbContext.flush_idle_tasks()
   in MySQL.GUI.Workbench.Program.timer_Tick(Object sender, EventArgs e)

Please, check if this problem ever happens with a newer version, 5.2.32.
