And the bug is?  I am baffled!  Please read the section on BUGS in the FAQ.
Acting as documented is not a bug, nor is giving an error message when a
function is used incorrectly.

A panel function is documented as

   panel: `function(x,y,...)' which is used to plot the contents of
          each panel of the display.

Note *contents*.  I don't think qqplot qualifies, so you get a message
about your error.  You probably want (untested)

panel.qqplot <- function(x, y, ...)
{
   res <- qqplot(x, y, ..., plot.it = FALSE)
   points(res$x, res$y)
}
