Description Mark Zhitomirski 2012-07-10 16:05:30 UTC

Headless VirtualBox craches on VNC connect

Reproducible: Always

Steps to Reproduce:
1. "emerge virtualbox" with "headless vnc -qt4" USE flags
2. start VM named e.g. "d6" with the following command: VBoxHeadless -s d6 --vnc --vncport 5903
3. See VM starting and printing some VNC messages as it boots
4. Connect to VNC
Actual Results:  
VBoxHeadless aborts and prints call stack having at top smth. like this:

...
/lib/libc.so.6(+0xf9767)[0x7f3c5327a767]
/usr/lib/libvncserver.so.0(rfbProcessNewConnection+0x104)[0x7f3c50d2f5c4]
...

Expected Results:  
VNC connects OK and displays running machine screen

Some analysis is here: https://bugs.archlinux.org/task/30401
Workaround: 
echo "=net-libs/libvncserver-0.9.9" >> /etc/portage/package.mask
emerge -N virtualbox
(this makes net-libs/libvncserver-0.9.8.2-r2 installed which works OK with virtualbox)
