Double sort icon when combined Bootstrap with Scroller

[spyhunter88]

I use both Bootstrap with Scroller and found it will make a blank line right under header and above all body's rows. If you don't click in header for sort, it will show a small blank space, but when you click to sort, it double the sort icon into this blank space. Only sort icon in there. I use latest DataTable (1.10.6) and Scroller (1.2.2).
I dont know this cause by latest version or an old issue.
I make a demo in jsfiddle but it doesn't work, but I think some one can make it works for me, I am not familiar with jsfiddle. Link here http://jsfiddle.net/fw6Looxz/.
