svn:keywords and HeadURL not set during a svn switch command

        Hello,

        I have the HeadURL keyword set for a file and would like it to
reflect the svn url for the working copy. But when I switch the working
copy to another tag, the keyword doesn't change.
        I saw a message on a mailing list archieve when Cristian van der
Leeden reports the very same case but I couldn't see the solution for
the problem.
        The original post I found is at:
http://www.contactor.se/~dast/svn/archive-2003-03/1846.shtml
        Is that really a bug in Subversion? Was it fixed? I couldn't
find an entry on the bug database either.
        Is there a workaround for that? Maybe a svn command that outputs
the HeadURL.
        Regards,

Ricardo
