I can confirm this bug on a Thinkpad T61p (lsusb says: ID 0a5c:2110 Broadcom
Corp. Bluetooth Controller) with Ubuntu 9.04 and KDE 4.2.2
and KBluetooth4 Version 0.3.
I started with gdb and run -nofork and then switched off the hardware switch.
(also happens after resume from suspend). Here the output and the trace:
