I'm far from an advanced user, but I use rebase fairly regularly for long running feature branches. As the parent branch continues along, I periodically rebase complicated feature branches so that I'm doing a number of small easy to handle conflict resolutions, rather than one almighty one at the end. I've never had any trouble, and I'd never considered it to be anything out of the ordinary or anything other than basic!
