``wrong'' depends on your situation. Your headset probably supports
both HSP/HFP and A2DP. By default HSP/HFP is support was used which has quite
crappy sound quality (8khz iirc), but has both input and output so it can be
used to make calls. A2DP otoh has decent sound quality, but doesn't have input
capabilities, so it's only suitable for listening to music. (Thanks bluetooth)
In my opinion, in the brave new future, pulse should use A2DP by default and
voip application should switch headsets into HSP/HFP profile when they need it.
Unfortunately, no voip app has this capability yet, so there is no obvious
right profile here.
One thing that should help though is that once you've switched the profile of
the headset to the one you like, pulse should remember it and use that profile
next time you connect the headset. Can you test if this happens correctly for
you ? If so then i think we should close this bug

Pulseaudio just detects when a bluetooth headset is connected to your machine.
You need to use some other tool to detect and connect it initially. My
bluetooth headset tries to automagically connect to my machine when i turn it
on, which makes things work nicely. Another option is to use the applet in
gnome-bluetooth which provides an easy way to connect to known devices
(assuming you use gnome ofcourse)
An idea is not responsible for the people who believe in it.
