This doesn't seem to be a bug in the ubuntu-docs package. I'm unassigning for now, hopefully your bug will be assigned to the right package in due course. In the meantime it would be helpful if you could give as many details as possible about the problem. For example, where you saw it, what you did before you saw the problem, etc.
