I personally have never been able to reproduce this problem.
Can anyone of you search for a file called "http_cache_cleaner.desktop" on your system and make sure if it has an entry called "X-KDE-StartupNotify = false"? If it does, can you then change that to say "StartupNotify = false" and see if the problem goes away?
I can see why X-KDE-StartupNotify will not work on non-KDE desktop environments, but a bunch of you are reporting that you are seeing this issue on a KDE desktop environment and that does not make any sense.
