RFC822 is quite clear on this. Take the example on pages 7 and 8:

        So, for example, the folded body of an address field
            ":sysmail"@  Some-Group. Some-Org,
            Muhammed.(I am  the greatest) Ali @(the)Vegas.WBA
        is analyzed into the following lexical symbols and types:
                    :sysmail              quoted string
                    @                     special
                    Some-Group            atom
                    .                     special
                    Some-Org              atom
                    ,                     special
                    Muhammed              atom
                    .                     special
                    (I am  the greatest)  comment
                    Ali                   atom
                    @                     atom
                    (the)                 comment
                    Vegas                 atom
                    .                     special
                    WBA                   atom
        The canonical representations for the data in these  addresses
        are the following strings:
                        ":sysmail"@Some-Group.Some-Org
        and
                            Muhammed.Ali@Vegas.WBA
        Note:  For purposes of display, and when passing  such  struc-
               tured information to other systems, such as mail proto-
               col  services,  there  must  be  NO  linear-white-space
               between  <word>s  that are separated by period (".") or
               at-sign ("@") and exactly one SPACE between  all  other
               <word>s.  Also, headers should be in a folded form.

This indicates that the cited address "George Bush bush@tree" is valid. The
interpretation according to RFC822 might not be the intended one, but that's
a different topic. The mailer creating these addresses should be checked and
corrected. It is most likely something like
	Dq$?x$x $.$g
instead of
	Dq$?x$x $.<$g>
in its sendmail.cf (incorrect definition of total addresses).
