recordPlot in 1.5.x, replayPlot in 1.6.0 problem

I have plots that were stored using recordPlot() in a fairly recent 
but pre-1.6.0 version of R that will not replayPlot() in R 1.6.0. The 
error message is
    Error in replayPlot(x) : invalid hex digit in color or lty


The plots were stored in June (2002-6-14), each as an element of a 
list named 'rpl'. The version of R that was current then is what I 
used. At that time I was able to re-display them.

Today, in R 1.6.0, when I try to re-display them, I get an error message:

 rpl[[1]]

Error in replayPlot(x) : invalid hex digit in color or lty

The plots did have lines with col='blue' and lty=2 in them. This 
little snippet of code executed today works
  > plot(1:5)
  > lines(1:5,col='blue',lty=2)
  > tmp <- recordPlot()
  > tmp
so there doesn't seem to be a problem if I work entirely within 
v1.6.0. Which suggests that the problem is in going from one version 
to the next.
