3.1-rc9: Xvnc segmentation fault/coredump

[Justin Piszcz]

Hello,

Summary: vncserver crashes with 3.1-rc9 when launching 
thunderbird and chrome (usually reproducible)

Problem: With 3.1-rc9 -- vncserver (both vnc-4_1_3-x86_linux) and the 
package in Debian: 4.1.1+X4.3.0-37 both core dump under 3.1-rc9 when I 
launch a couple of applications, thunderbird and chrome, these 
applications were also upgraded around the time I went to 3.1-rc9 so I 
cannot be certain which is causing the crashes.  I cannot change the 
kernel for a while, machine is in production now; however, I have been
following the 3.1-rc's for awhile and all were OK (ran -rc8) for 
the longest until -rc9.  There appears to be no quick/fast 
debug package available for vncserver; however, I will show/describe it as 
best as I can.

1. Start vnc: vncserver -geometry 1920x1200 :1 -depth 24
2. Launch latest thunderbird, then chrome, then Xvnc crashes, dumps core.

Core with Debian's 4.1.1+X4.3.0-37
-rw------- 1 bob users  60551168 Oct 10 05:01 core.Xvnc4.7121

Core with realvnc's latest VNC on website (4.1.3):
-rw------- 1 bob users  67252224 Oct 10 05:11 core.Xvnc.9631

Obviously without a debug version, the output is not meaningful, however, 
I was curious if ayone had seen anything like this with 3.1-rc9?

Core was generated by `Xvnc4 :1 -desktop p34:1 (bob) -auth /home/bob/.Xauthority -geometry 1920x1200 -'.
