[Laszlo-user] ide4laszlo

I am trying to get this going on Ubuntu. So far I have jdk1.5
Eclipse3.1(from Ubuntu). I install all web tools using the update site
and then the 0.2.0 Laszlo plugin for jdk1.5. Everything seems to now
work fine and I can start to drag components to the page etc. However,
when I try to use anything in Resource or Media of the pallette
everything locks up solid, requiring an X restart and a kill for java
which is now out of control.

So I try this: Download the Eclipse SDK from Eclipse, install web tools
as above and then the Laszlo ide plugin. This does not work at all and
gives the  error below. Can anyone help me sort out either of these
problems?

regards
Garry
