Some more technical details:

You can find a part of Lydia's startup log here, it clearly
illustrates the problem:

http://lydiapintscher.de/tmp/amarok2.log

As you can see, getDirsToScan() lists about every directory on her
harddisk, including system folders:

amarok:               "/usr/lib/kde4/share/icons/Locolor/"
amarok:               "/usr/lib/kde4/share/icons/Locolor/16x16/"
amarok:               "/usr/lib/kde4/share/icons/Locolor/16x16/apps/"
amarok:               "/usr/lib/kde4/share/icons/Locolor/32x32/"

And then we can see that the whole operation takes over one minute:

amarok: END__: void ScanManager::startIncrementalScan() - Took 65s

I've looked at getDirsToScan() and tried to think of an explanation
for the behavior, but I'm really clueless as to what's going on. Also
I could not reproduce the problem here on my computer, much as I
tried.
