Yup seems so. I checked it from Mobile, Tweetdeck and the Web. All the tweets are duplicated meaning you can see it like 5 to 10 times in the time line. Interesting how it’s getting duplicated though they are at same time.May be that’s not that factor.
Update : Looks like the problem is when the tweet is getting published. Its throwing an error but the tweet gets published but since user is getting an Internal Server Error it gets published again.
