Original report text:
"I am using fully updated Kubuntu 9.10 with KDE 4.3.2. I copied to clipboard a URL and tried to use the "Send --> Clipboard Text" feature of kbluetooth. The device selection window appeared, I selected a device and when I clicked send kbluetooth crashed. I tried this with other recipient devices and it happens too.
I am using a Dell XPS M1330 with the Dell 355 Bluetooth module."
