Xvnc crash

[Peter Clifton]

Hi,

I've been trying to get a thin-client setup with Gnome's GDM and Xdmx as
a proxy X server.

When invoked with the command line (security disabled for testing):

/usr/bin/Xvnc :1 -query localhost SecurityTypes=None -ac -depth 24

After a short time using the session, I get a crash:

Program received signal SIGSEGV, Segmentation fault.

This is with Xvnc as shipped with SuSE 10.2

xorg-x11-Xvnc (SuSE package version 7.1-33.3)

Are there any known bugs in VNC which could cause this? Any fixed
already in a newer version?

If not, how is best to proceed debugging the problem?
