I've got the exact same issue, has someone come up with a solution or something?

Status changed to 'Confirmed' because the bug affects multiple users.

Same for me. Interestingly it was working fine when I was running kernel 3.11 with Trusty. As soon as I updated the kernel to 3.13, I started receiving this error. Looks identical to the problem they are having with Mint 17(Bug 1334457 ). I assume for the same reason. The text returned from the terminal is:
