Comment(by coling):

 Sorry for the late reply.

 I don't really see anythign from that log that indicates that PA has
 frozen. It's mearly PA being loaded again for some reason while it is
 already running. Quite why this is happening it's impossible to tell.

 I wouldn't rule out the fact that something in GNOME3 is relying on PA in
 a way that is incorrect. In order to check this, you should ensure that
 libcanberra is not used on your system by setting {{{
 export CANBERRA_DRIVER=null
 }}}
 in your ~/.bashrc

 This should prevent any login sounds and any other desktop event sounds
 including IM messages, new mail notifications etc.

 You should confirm this via:
 {{{
 pacmd list | grep canberra
 }}}
 after logging in. It should produce no results.

 Once you have confirmed that this prevents the freeze, you will likely
 have to debug libcanberra code to work out what is wrong.

 You should also log in to your system via SSH to check to see whether it
 really is PA that has frozen (ask it things like "pactl stat" etc.) or
 whether it is a misbehaving client (i.e. canberra) that is to blame.
