USB disconnect crashes VBoxSVC

Description

After upgrading to 4.0 I experienced crashes of my VMs. After investigating a bit, I found out, that it always happens when I switch from my Linux VM Host to my other Desktop PC by tapping my Belkin Display and Keyboard Switch.

This error is reproducible. As long as I do not activate the KVM switch, my VMs run stable, but as soon as I switch to the other PC, their VBoxSVC service crashes. See the attached dmesg.log file for some messages.

I'm using VirtualBox 4.0 under Ubuntu 10.10, Kernel: Linux foo 2.6.35-24-server #42-Ubuntu SMP Thu Dec 2 03:58:11 UTC 2010 x86_64 GNU/Linux

The guest VMs (Windows and Linux) do not have USB support enabled.

See the attached VBox.log for crash details.

Would it be possible to get a core dump of the crashing VBoxSVC process?

I've attached a core dump, although I had to deviate from the given core dump instructions as the crash only occurs when running a headless VM. I started the VM with

VBoxManage startvm $VMUID -type headless
