If you’re using a recent KDE version you’ll notice that Wuala’s Copy & Paste feature doesn’t really seem to work anymore. Instead of using the contents you specify within the application (say, files and folders) it’ll always use the contents of Klipper.
That’s pretty annoying if you don’t know that the contents does indeed come from Klipper. So, just clear your Klipper history and you should be fine.
