I have a Linksys (Cisco) USBBT100 Bluetooth 1.1 Adapter which has a 1.2 dBi

Belkin F8T017. It used to work (but not for audio) with older versions of
bluez 4. I tried it again with bluez 4.34 and now a simple "hcitool scan"
makes bluetoothd core dump.
Could you try and see if
this is reproducable with the latest git? You don't necessarily need to install
it, just compile with "./bootstrap-configure && make" and run the compiled
bluetoothd directly from the tree.
It appears that you need to run ./src/.libs/bluetoothd with valgrind. This is with the latest version from git.
It didn't crash with "hcitool scan" but rather when I tried to open an audio device or run obexftp. I have never managed to open an audio device or run obexftp using my USBBT100. bluetoothd always crashes. I have no problems when I use my F8T017.

This time "hcitool scan" did crash bluetoothd. It has been a long time since I last used gdb. Is there something I should do to get a better backtrace?
