CNUT and FC3: installed fine, but nothing on execution

I’m having troubles getting CNUT working on my Fedora Core 3 workstation. The instalation went smoothly, by the book. But when I run the “networkupdater” command, the CNUT GUI does not start.

Here’s the output of running networkupdater:"

[ahull@hal ~]$ networkupdater
Starting application…
[ahull@hal ~]$

I tried it as root also, but with the same results.

When I look at my process list CNUT is running, but with several defunct processes that I’m assuming are children of CNUT.
[ahull@hal ~]$ ps -aef | less

I’ve got the latest versions of Java and Perl installed.
Any ideas?
