RTE #1009 in flashx.textLayout.container::TextContainerManager when scrolling

I can repro it successfully, so I also think it's a bug. Filed Vellum bug#2995727 for tracking this. But i don't have workaround at this time.

For those who are not logged to the bugtracker :

TypeError: Error #1009: Cannot access a property or method of a null object reference. at flashx.textLayout.container::TextContainerManager/http://ns.adobe.com/textLayout/internal/2008::addInlineGraphicElement() at TMContainerController/addInlineGraphicElement() at flashx.textLayout.container::ContainerController/http://ns.adobe.com/textLayout/internal/2008::updateGraphics() at flashx.textLayout.container::ContainerController/http://ns.adobe.com/textLayout/internal/2008::updateCompositionShapes() at flashx.textLayout.compose::StandardFlowComposer/updateCompositionShapes() at flashx.textLayout.compose::StandardFlowComposer/updateToController() at flashx.textLayout.container::ContainerController/updateForScroll() at flashx.textLayout.container::ContainerController/set verticalScrollPosition() at flashx.textLayout.container::TextContainerManager/set verticalScrollPosition() at spark.components::RichEditableText/commitProperties() at mx.core::UIComponent/validateProperties() at mx.managers::LayoutManager/validateClient() at mx.core::UIComponent/validateNow() at spark.components::VScrollBar/http://www.adobe.com/2006/flex/mx/internal::mouseWheelHandler() at flash.events::EventDispatcher/dispatchEventFunction() at flash.events::EventDispatcher/dispatchEvent() at mx.managers::SystemManager/mouseEventHandler()

Test case: http://knux.biki.fr/bronx/InlineGraphicTest.mxml

Steps to reproduce:

1. Run InlineGraphicTest.mxml using TLF 3.0 at http://sourceforge.net/projects/tlf.adobe/files/3.0/current/

2. Try to scroll (use mouse wheel for example)

I just try using the svn version (trunk) of TLF, same issue

Anybody can help ?
