While browsing the Unanswered Questions I noticed this:
I clicked through to the question and the user in the picture is nowhere to be found.
I also noticed a similar issue with this question, so it is not specific to one question.

The question list shows you the user who most-recently answered the question or edited a post in the thread.
In both of these cases, however, the users modification (an answer) was subsequently deleted. If you have the reputation to see deleted posts, it would be somewhat more obvious.
It's just a quirk of the software, not (as far as I know) a bug.
