CSS properties like "width" apparently are truncated to integer values in KHTML.  I have a website with three items with widths of 33.333% (relative to a parent div), and Konqueror seems to use 33% instead -> I can clearly see the remaining 1% not being filled.  Opera has the same problem, Mozilla and IE6 do it right (i.e. fill the div completely with 3 times 33.333%).  

Example: http://www.epidauros.be/ .  There are three <li>'s on the top: "De Nacht", "Historiek" and "Gastenboek", each having "width: 33.333%" (in default.css, under "ul#menu li"), but if you hover over "Gastenboek", you can see the remaining 1% not turning grey.
