When I copy some files in Dolphin (Ctrl+C), plasma-desktop is blocked for about 10-15s. During this time the desktop does not repaint when I move the dolphin window arround, and I can't use the task-bar or k-menu, however Dolphin stays functional.

I was able to get a stacktrace while plasma was blocked:

I still experience this with 4.5.4 and dbus updated to 1.4

Its quite annoying, every now and then plasma is unresponsive for 20-30 seconds after copying content into the clipboard.
