The report was for Emacsen built as
GNU Emacs 22.2.1 (i486-pc-linux-gnu, GTK+ Version 2.12.11) of
2008-10-17 on raven, modified by Debian
and development snapshot version
GNU Emacs 23.0.60.1 (i486-pc-linux-gnu, GTK+ Version 2.12.11) of
2008-10-18 on elegiac, modified by Debian
and I verified here that it crashes with a negative argument for all
versions I keep personally.
BTW, Richard apparently once tried to make `move-to-window-line' handle
scroll margins but failed somehow.
