This has been discussed before (http://lists.suckmore.org/dev/1006/4579.html),
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 Wayland 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.
