Same problem here. Kbluetooth crashes maybe 30% of the time when resuming from
suspend to ram. I'm not sure but it seems that running kbluetooth from gdb
reduces the crashes.

# dpkg -l | grep kdebluetooth
ii  kdebluetooth                             1:0.4~rc1-0ubuntu2                
                      KDE Bluetooth Framework
# uname -a
Linux T61ubuntu 2.6.31-17-generic #54-Ubuntu SMP Thu Dec 10 17:01:44 UTC 2009
x86_64 GNU/Linux

Here is some gdb output I managed to get. First using my Logitech dinovo mini
and later suspend to ram.

gdb kbluetooth
