R help - Mar 2010 - StatEt: Error R Object Browser Update java.lang.NullPointerException

Hello,

I'm trying to use StatEt on my kubuntu karmic system.  I've set 
everything up according to the website and a guide pdf I've got, but 
when I start the R session, or issue a command, I get a "An internal 
error occurred during: "R Object Browser Update"." error;

Any ideas on what to look at or try next ?

java.lang.NullPointerException

Have you managed to resolve this? I get the same error on Karmic Koala as
well.
