Note that for display purposes, it is not necessary that the displayed window's buffer == current_buffer, except for text property lookup. So, let's only set that buffer temporarily here without doing a full Fset_window_buffer. We must also change w->pointm, though, because otherwise an assertions in unshow_buffer fails, and Emacs aborts. */ but I can't find a useful hint in the backtrace. I don't even understand why a buffer should get killed here. martin
