[DevExpress Support Team: CLONED FROM T700699: Exception on loading and/or scrolling]
As I said this is a race condition so it's very difficult to make a video when the error occurs.
Also it seems to make no difference which pdf files you use.
I have attached a simple test project. Place some pdf files in the DemoFiles-SubFolder and use the Arrow-Key to navigate through the listbox and than close the application.
Sometimes the ReportMemoryLeaksOnShutdown reports memory leaks in your component.
