KDE VNC server crashes

[Rik Scarborough]

I'm having a problem with KDE's VNC server under FreeBSD.

I can connect to one machine that is running KDE and set to allow
uninvited guests, but when I disconnect from that machine the VNC server
(krfb) crashes with the following message.
    The Application unknown (krfb) crashed and caused the signal 11
    (SIGSEGV).

The trace is: 
(no debugging symbols found)...(no debugging symbols found)...
...<15 identical lines cut>...
(no debugging symbols found)...(no debugging symbols found)...

versions from portversion
    kde-3.1.2_1
    kdenetwork-3.1.2
    XFree86-4.3.0,1

I'm using FreeBSD 4.8-RELEASE #0

Any ideas of what I'm doing wrong?

Thanks,
