Why is my Subaru stuttering after a fillup?

Does anyone have any ideas about why my 2003 Subaru Outback stutters on acceleration for the ten or fifteen minutes after I fill it up with gas?

For the past few months, I've noticed that in the short period after I fill up my car with gas, it stutters on acceleration -- not terribly, and not so much that I feel like I'm in danger of stalling, but definitely a noticeable stuttering that wasn't there before. Like I said, this only ever happens for the ten or fifteen minutes after I fill up, and then never again until the next fill-up. I don't have any stuttering or idling problems in the cold, immediately after starting my car normally, or any of that; my check engine light isn't on (and doesn't come on during these periods), my gas cap is nice and tight, and I was last serviced about 6K miles ago.
A few details: the car is a 2003 Subaru Outback Limited Edition with a manual transmission, I fill it up with 87 octane gas (as I always have), no major driving pattern changes in a few years. The car has less than 50K miles on it to date.
I'm not the most trusting person when it comes to my local Subaru dealer (long story), so I was looking for a little advice as to what might be causing the problem before I bring it into someone to take a look. Any auto mechanics out there who have a few ideas to toss into the ring?
