VirtualBox segfaults with Harmony Software when accessing USB devices (Windows Vista on Linux host)

[dejan]

I'm trying to use a Vista VM to update Harmony remote controls and when the update is about to finish on one of the devices the machine simply segfaults - here are the lines in /var/log/messages before and after the crash:

The update causes the disconnect and the disconnect causes the crash (I believe).

I'll also attach the VBox.log file from the Virtual machine.

I can reproduce this by simply unplugging the USB cable without doing anything else with the Vista VM running, it immediately crashes.
