Hmm.. Mine wasn't a fresh install. I Updated from 13.04, and i don't remember messing with TUN/TAP. I'll try w/ Kali linux to check.
You're missing the TUN module - ...Without the kernel module, the ioctls won't work.
@martywd, You're absolutely right! Thanks for catching that. I have just released a fixed version which will use the correct nameservers.
