It is not a skype issue. This is before skype is even running. 

Process is something like: 
Computer boots up, loads snd-bt-sco module from modules, starts
bluetooth
login as user, 
startx, 
start terminal, 
su, 
edit /var/lib/bluetooth/<BTaddress>/linksys and delete headset line
start another terminal as user
badger at owl:~$ btsco <BT headset Address>
btsco v0.41
Device is 1:0
Voice setting: 0x0060
<request pops up for pin>
RFCOMM channel 1 connected

Skype is not running. 

Turn off headset
RFCOMM channel lost

Turn on headset
badger at owl:~$ btsco 00:0A:94:90:D4:ED
btsco v0.41
Device is 1:0
Voice setting: 0x0060
Can't connect RFCOMM channel: Permission denied

Switch to su terminal and edit /var/lib/bluetooth/<BTaddress>/linksys
and delete headset line and then 

badger at owl:~$ btsco 00:0A:94:90:D4:ED
btsco v0.41
Device is 1:0
Voice setting: 0x0060
<Request pops up for pin>
RFCOMM channel 1 connected

For some reason, there seems to be some sort of issue with the
negotiations when using the pin information stored in the linksys file.
When pin information is deleted, then it re-requests the pin and all is
happy.

Possibly not even then, I am sure I read something about a hook
somewhere in the latest kernels which allow you to swap them whilst
running. I could be wrong here though.

Thanks and Regards,
