Thank you for your report! I have seen this error several times, but unfortunately couldn't reproduce it. But anyways, I did a fix in a place where this exception is thrown, so you can update the plugin to 0.8.3 version and if the same issue appears, please reopen this ticket. Thank you!

OK, thanks. I've seen this exception only once as far as I remember, so I guess I'm not seeing it soon anyway.
