If finalize chardev-msmouse or chardev-wctable is called immediately after init it cases QEMU to crash with segfault. This happens because of QTAILQ_REMOVE in qemu_input_handler_unregister tries to dereference NULL pointer. For instance, this error can be reproduced via `qom-list-properties` command.
