I have seen this symptom more than once but this is the first time I've had apport enabled and had it happen so I do not know if those other boots were the same problem. Bug 627011 is concerning the macbook model before mine but it seems likely this is a dupe of that one so there are other people having the issue. I didn't initially add to that bug because I wanted to make sure we were having the same problem.
