This has been discussed before (,
and I've been using a bodged version of surf, which works around the bug by
disabling the error handlers when it brings down the window. I haven't used surf
for a while _and_ I have no X11 experience so I'm not sure whether it works
(haven't tested it thoroughly enough), but I've attached a diff, it
should apply cleanly
to 0.4.1.
