Vaadin 6, modal window, crashes IE for some users

I am using Vaadin 6.8.7 and have code that populates and displays a modal window popup but for some reason the data that is sent to the browser seems to cause IE8 to crash. Here is roughly the modal window logic.

	Window subWindow = new Window();
	return subWindow;

This works fine for most users but there is a small subset where IE will crash saying Internet Explorer has stopped working. An Application Event Log error gets logged with the following:
Faulting application name ieexplore.exe, version:8.0.7601.17514
Faulting module name: mshtml.dll, version:8.0.7601.17940
Exception code: 0xc00000fd
Fault offset: 0x000a8367
Faulting process id: 0x%9
Faulting application start time: 0x%10
Faulting application path: %11
Faulting application path: C:\Program Files (x86)\InternetExplorer\iexplore.exe
Faulting module path: c:\Windows\SysWOW64\mshtml.dll

Internet reseach has mentioned resetting IE settings and running IE in No Addon mode to isolate the problem. The issue still occurs when taking these steps. I was wondering if anyone else has come across this peculiar issue.
