I feel this is really simple and I'm just a total noob, but I've been searching for this for 3 hours now and can't find it. I'm running Kubuntu 9.04 and I think my Qt version is 4.5.0 I'm pretty sure. I'm on an iMac G5 and my KDE icons are glitchy (the icons are basically inverted colours). I found a bug report saying this is Qt related and is fixed in version 4.5.2.

My problem is... hah well I have no clue how to upgrade Qt and 3 hours of searching hasn't giving me anything... Any help? Thanks
