I go through the whole installer, and when it gets to installing packages, it does it's thing, and then says "preparing to install", then the screen goes blank, and it writes out this:
(Anaconda:94) : GnomeCanvas-Critical ** : file gnome_canvas_paths_def.c:line1142
(gnome_canavas_path_def_any_closed):assertion 'path!+NULL' failed.
installer exited abnormally
you can safely reboot your system (or something like that)
