I think I have same kind of problem..

I have mpd server streaming music at home and I listen to it using N900 often when going home from work. On previous PR 1.1 this did not happen, but happens quite often on PR 1.2. Using 3G network.

If someone wants to try the same route , here's what I have noticed that has happened at least couple of times:
- I leave work - I work at the Cable Factory, Ruoholahti, Helsinki, Finland
- when I'm at the elevator (staircase C), I'll start the stream about when elevator reaches street level
- I walk through the yard
- player stops when I turn at the end of building towards the tram stop, I'll press play and music continues
- I walk to Ruoholahti metro station
- player stops again when I'm at escalators downwards, halfway down. Again I just press play and stream continues
- after that I don't remember the player stopping for the rest of the trip. There are couple of spots where player re-buffers stream as 3G network drops out, but from these the player recovers successfully.

One thing to note is that I also open ssh connection when leaving work and that stays open at least through the beginning of trip where media player stops, so that rules out IP address changing at least. I think my IP address has changed at least sometimes after going through the spot where 3G network does not work and that does kill the ssh.

I do have headphone daemon installed (and other stuff too, too many to list here).
