Strange.
Do not understand how it can conflicts with S10. I have not run S10 my self so I don't know that it does.
But since it happens during right click it, S10 probably installs a shell extensions that is called when showing the context menu.
But nice to hear that it works in the 2.1RC. But no issue around shell extensions has been changed for 2.1 (I think.. not sure).
But I will take a look at the dump you sent later tonight and see if it give any hints on that can have caused it.
Maybe is still crashes on some files and work some others.. If get the crash again, let me know.
