3.1-rc9: Xvnc segmentation fault/coredump
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.

RE: 3.x/libc6 -- out of ideas -- launching chrome results in an immediate crash of Xvnc everytime [SOLVED, well root cause found anyway]
Hi, It came down to this Google Chrome extension: Name: Extensions Manager (aka switcher) Version: 0.1.6.95_0 When this extension is enabled in 64-bit Linux when I launch Google Chrome on two separate machines (both 64-bit/Debian), it crashes Xvnc, when I disable/remove this extension, Xvnc no longer crashes (at least it has not yet :-)) All of this hassle due to 1 bad plug-in; in any event though there is a bug in X/VNC, an application should not crash VNC. Just a heads up to anyone else who sees this problem. Justin. ___ VNC-List mailing list VNC-List@realvnc.com To remove yourself from the list visit: http://www.realvnc.com/mailman/listinfo/vnc-list
