Thanks for your report. This is not a known problem. Since what you 
see happens in an Apple kernel extension for HID devices (which will 
not be used for the Sony BD Remote) and Remote Buddy also doesn't and 
can't access any functionality in the IOBluetoothHIDDriver, I can't 
see a connection to Remote Buddy.
I also tried to generate the cleartext version of the backtrace using 
the usual debug tools, but couldn't since using previously working 
ways to do this no longer work (the  and Apple's new set of 
instructions (=> http://developer.apple.com/technotes/tn2002/tn2063.html) 
fail with a
kextload: cannot resolve dependencies for kernel extension /System/ 
Library/Extensions/IOBluetoothHIDDriver.kext
error message.
Since all of OS X Bluetooth code is strictly closed-source, only Apple 
will be able to get to the bottom of the problem. Apple has made a lot 
of changes to Bluetooth throughout the Leopard releases and I'm sure 
they continue to make more, so you should definately submit your crash 
report to Apple, so they become aware of the issue.
As you seem to have a lot of issues that noone else has previously 
reported: are you using any system modifications, any hacks like f.ex. 
haxies, any input managers or the like?
Are you using a Bluetooth USB stick or a Bluetooth module by Apple? 
Any other Bluetooth devices or software?
Best regards,
