[R] Need Help with StatET Error/Bug? on Ubuntu 8.10 amd64

[Ken-JP]

Hi,

I posted this message on the StatET-user board last week, but it looks like
a ghost-town...

I have a bad feeling that there is some code in the plug-in which doesn't
work well with my environment, but if I am lucky, maybe other users have
worked around this problem somehow - I am hoping that my setup is the issue.  

Note: very similar StatET setups on 32-bit XP Pro and Vista run flawlessly.

Has anyone else run into this problem and/or found a way around it?

Ubuntu 8.10 intrepid amd64
Java(TM) SE Runtime Environment (build 1.6.0_13-b03)
Java HotSpot(TM) 64-Bit Server VM (build 11.3-b02, mixed mode)
R 2.8.1
Eclipse 3.4.2
StatET 0.7.2.b200812051430sw

---------------------------------------------------------------------------------------- 

When I start up the R Console, I get a java.lang.NullPointerException inside
Eclipse in the form of a popup warning.

Six icons right of the Console-tab fail to appear:

Cancel the current task
Terminate
Remove Launch
Remove All Terminated Launches
Clear Console
Scroll Lock

Every time the Console gets focus, I get the NullPointerError exception -
probably an attempt to refresh the icons.  After a while, the Eclipse IDE
loses focus and becomes unusable.

Looks like it's happening around:
