x0vncserver Invalid argument (22)

I am trying to use x0vncserver on FC4 so that I can access my running X
display using VNC. However, when starting I get the following error:

[raman ~]$ x0vncserver -PasswordFile /home/raman/.vnc/passwd \
-rfbport 5906 -display :0 -Log *:stdout:100

 main:        XTest extension present - version 2.2
 VNCServerST: creating single-threaded server x0vncserver
 main:        Listening on port 5906
 VNCServerST: shutting down server x0vncserver
 main:        select: Invalid argument (22)
~ImageCleanup called

IIRC, x0vncserver worked for me on FC3.

Any ideas?

Cheers,
Raman
