The only yelp function in the stack trace is yelp_view_dispose, which should only be called when you close a window. What it looks like is that the WebKit view is shutting down and in the process sets the adjustment that's used to scroll it, and that change is being reported to the accessibility system, and a crash is happening somewhere in there. At any rate, I think the bug is somewhere deep in the GtkRange accessibility code.
