since Remote Buddy can't take any effect on the performance or pairing 
of Bluetooth devices in the kernel (the Bluetooth kernel API is not 
documented, so you also can't write drivers for it or control it in 
any way), I can't see how Remote Buddy could influence pairing, let 
alone crash your computer.

Could you please send me the panic logs located at

/Library/Logs/PanicReporter/ (OS 10.5.x) 
/Library/Logs/panic.log (OS 10.4.x)

and a system profile (start /Applications/Utilities/System 
Profiler.app > Save as.. > Send the file saved) to info@iospirit.com 
respectively, so I can have a look and forward them to Apple?

You can turn off Remote Buddy's Bluetooth driver support btw, by 
turning off the option of Remote Buddy searching for remotes on 
startup (=> Preferences > Hardware > Bluetooth Receiver).

If you wish, I can also send you an older version in reply to that 
email.

Best regards, 
Felix Schwarz
