Newsflash: looks like a buffer overrun bug to me.
In _xcb_in_read_packet(), _xcb_list_find() returns an
XCBReplyData struct containing garbage from some
previous read() call:

$39 = {
  cond = {
    __c_lock = {
      __status = 134628032,
      __spinlock = 1768303993
    },
    __c_waiting = 0x2d646578,
    __padding = "medium-r-normal--16-120-100-",
    __align = 3474577016499482673
  },
  pending = 1,
  error = 0,
  request = 38,
  data = 0x0
}
