GWT Browser blank and Compile/Brows button greyed out

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install Fedora 9
2. Install Eclipse v.
      Eclipse Platform

      Version: 3.4.1
      Build id: M20080911-1700
3. Install GWT v. 1.5.x (tried with 1.5.3 and 1.5.2)
4. Import "Hello" Example.
5. Right-click Hello.gwt.xml -> Run As -> GWT Hosted Mode Application

What is the expected output? What do you see instead?
Expected:  Something in the GWT Browser
Instead:   URL:
http://localhost:8888/com.google.gwt.sample.hello.Hello/Hello.html
   Just a blank window and "Compile/Browse" button is greyed out.

What version of the product are you using? On what operating system?
Linux, cypal.studio.for.gwt-1.0.zip

Please provide any additional information below.

1. Running $GWT_HOME/samples/Hello-shell works fine.

2. When I click on the browser in both GWT browsers started manually and
from eclipse, I get the following code to STDERR:

   (gecko:8384): GLib-GObject-WARNING **: gsignal.c:1019: unable to lookup
signal "activate" of unloaded type `MaiAtkObject'

   (gecko:8384): GLib-GObject-CRITICAL **: g_signal_emit_valist: assertion
`signal_id > 0' failed

...but as mentioned, the manual Hello-shell works fine even though this
error is displayed.

3. This is my first GWT project so I'm sure this error is due to a simple
configuration parameter or obvious environment variable that I've missed.

Have you solve the problem yet? 
I've got the same problem but I use Ubuntu 9.0.4. 
Please suggest how to make the gwt blowser work. Thanks

Nope - given up for now - no support I guess :(
