FreeBSD Port: emulators/virtualbox-ose exited on signal 11 random crashes on screen update using VNC

[Ron Thomas]

Have an intermittent crash that I haven't been able to figure out the
trigger for.... perhaps a race condition?  Happens frequently, usually when
lots of stuff is happening on screen.  Core dump shows that it always fails
at the same line of code.
