The horizontal scrollbar appears only in IE7 even when overflowing: hidden set

Question

I hit my head about it.

I have an alarming horizontal scrollbar that only appears when viewing my site in IE7:
http://www.regia.it

I tried and tried to stop this due to use overflow:hiddenon mine div, but for some reason I just can't find the cause of the problem.

Any help is greatly appreciated.
