>While debugging I encountered what seems to be accessibiliy-related exceptions in ScAccessibleEditLineTextData::GetTextForwarder; backtrace attached:
>
>Exception thrown at 0x75D1A6F2 in soffice.bin: Microsoft C++ exception: com::sun::star::uno::RuntimeException at memory location 0x01B8F240.
>
>This occurred a couple of times before I got to the loaded application with sheet. It goes through SfxWorkWindow::UpdateObjectBars_Impl and SfxWorkWindow::UpdateObjectBars_Impl into accessiblity-related code (see trace).
>
>mpTxtWnd and mpForwarder are both null, and so pTextForwarder is null in AccessibleTextHelper_Impl::GetTextForwarder
>So it throws uno::RuntimeException("Unable to fetch text forwarder, model might be dead", mxFrontEnd); [mxFrontEnd is also null]
>
>Not sure if it is usual for this to occur or if it has relevance to the crash, but I figured if something failed in creating the accessibility events, it might also cause problems when accessibility-related stuff is being torn down.
