Hmm that's actually pointing to WebKit, rather than lightdm, which is not what I was expecting to see. So it is possible that this is a WebKit bug. But you don't have any debuginfo installed, so there's no way to know where it's coming from. If you install debuginfo and try again, then we'll know for sure. That will fill in all the n/a frames:
