Steps to reproduce:

Open http://www.hwsuite.com/ and scroll down to the footer.

or

	        <option value="http://el.hwsuite.com">Ελληνικά</option>
	    </select>




Actual results:

Select opens with about 6 empty lines.

And another side effect: with firebug (not 100% sure the reason in it) when I click the select, Firefox eats 100% CPU.


Expected results:

1. Height of the opened select must fit option count.
or.
2. Opened select must have horizontal scroll.
