[R] Wrong symbol rendering in plots (Ubuntu)

Hi I am having problems with the rendering of scientific symbols (mu and 
degree) in my plots. Whenever I use these symbols they are rendered 
changed (mu is changed to the proportionality symbol and degree is 
changed to something resembling a gamma) in the X-device. If I make a 
pdf of the plot and open the file in Evince or Okular symbols are also 
rendered wrong, however if I open the file with Xpdf or Acroread they 
are rendered correctly.

I did not have this problem before, it arose after I upgraded both R and 
my system (Ubuntu karmic koala to lucid lynx), so I can not tell for 
sure if the problem is R-related or Ubuntu related (I have posted in a 
Ubuntu forum also http://ubuntuforums.org/showthread.php?t=1325289).

Please let me know if you have any idea of how to fix this, or if you 
can confirm this is not an R-related issue.

Thank you very much in advance,
