Bug in Kernel 2.6.4?

[hamish]

Hi all.

I got this message from my Kernel tonight when unplugging my USB 
BlueTooth adapter form my laptop. It WAS working fine, then suddenly 
after transferring about 10 files using kbtobexclient, I kept getting 
messgae about unable to connect transport frm the obex client software. 
Upon unplugging the adapter I got the following in my messages file...

Thought someone might be interested...
