Kubuntu KDE 4.5.0 Glitches
When it comes to upgrading my Kubuntu environment I am typically an early adopter. This includes backported KDE releases. Naturally, this also means that I am regularly bitten by bugs (which are most common in .0 releases).
Unfortunately, this just happened with KDE 4.5.0 where the systray is completely unusable when hosting icons for non-KDE applications (such as Skype or Google Desktop). As it turned out, a Qt bug is responsible for the mess-up and a fix is already available in the Qt 4.7.x development branch.
