Problem with scroller + swidth using json

I posted a discussion on datatables forum but this is probably the best place for my problem.

I have the same problem as described in http://datatables.net/forums/discussion/19089/datatables-bautowidth-false-not-working-when-sscrolly-is-set but it's still not working with the nightly build (which was the solution on that discussion). When loading through json/ajax header width is ignored and the columns get resized. You can even see how the column has one width before loading the json data and one after. I've made a fiddle showing the problem, I'd appreciate any help!

You can see the discussion here: http://datatables.net/forums/discussion/24259/column-swidth-not-working-when-scrolly-is-set-and-json-is-used#latest

Thanks!!!

Start by reproducing the issue in the linked jsfiddle, using Scroller with sScrollY, sWidth, bAutoWidth false, and JSON/Ajax loading. Compare the column widths before and after the data loads, and review the linked DataTables forum discussions for context. Done means configured header widths remain unchanged after JSON data is loaded.
