Bluetooth headsets fail to trigger pulseaudio consistently (Long)

Hi guys, I have an issue with bluetooth on Opensuse 11.2; Pulseaudio
0.9.19, Bluez 4.56, KBluetooth4 (I have also used gnome-bluetooth and
have exactly the same symptoms, issues and reliability) and supplied
graphic tools. Kernel 2.6.31.5-0.1-default.

My process is to start Kbluetooth4 and plug in the adapter (MSI Star
Key, details of hci0 follow).

I have 2 headsets, Jabra BT2040 and VBT185Z. Both of them have worked
well several times before with the same adapter. I press the button on
the headset and allow them to pair. Set always trust. Monitor status
from Kbluetooth4 which works as well as gnome-bluetooth in monitoring
status, connected, trusted etc. No problem here. Headsets connect pretty
much reliably.

The dump from the connection is listed below.

Now comes the problem: I use PulseAudio manager to monitor the
activation of the sink and source when the headsets connect. The default
sink is auto_null and the default source is auto_null.monitor. Once in
about 50 (fifty) connections pulseaudio sees the bluetooth connection
and the sink and source are activated away from the defaults and the
headsets become audio input and output addressable through alsa. The
rest of the time sink and source do not change.

Below I have added the hcidump and below that is the log from the failed
connection. Thanks for any assistance.
