This happens in E with software compositing, since E's commit
5702f0975e890f07cfb. E should be fixed shortly but segv is not
acceptable. Without segv E is still massively broken so it's
not like the bug would be hidden (large black areas in windows,
after switch vdesks with enough windows).
as per mailing list discussion about dropping xcb support now. it
hasn't been complete for a long time, thus not recommented for being
turned on. as we are moving to a wayland world xcbmakes even less
sense. as agreed, time to clean up a bit and remove a distraction as
well as not well tested code. this also updates po's too.
