Thanks for the report, but I cannot reproduce this with Emacs 23.3 on
GNU/Linux. cua--register is a variable, not a function. It's hard to see
how this error could happen. It almost looks like your cua-base.el has
been mis-compiled, since the only reference to cua--register in
cua-cut-region is:

(cond
   (cua--register
    (copy-to-register cua--register start end t))
    ...)
