Logfile from local PA daemon, from start till crash.

Description of problem:
Netowrk play to remote PA instance always fail. Remote PA output is very choppy and edns after few seconds, when _local_ PA daemon dies with following message:

I: module-tunnel.c: Server signalled buffer overrun/underrun.
E: source-output.c: Assertion 'pa_frame_aligned(chunk->length, &o->source->sample_spec)' failed at pulsecore/source-output.c:392, function pa_source_output_push(). Aborting.


Version-Release number of selected component (if applicable):
local PA version (where I have Totem playing music): pulseaudio-0.9.13-6.fc10.x86_64
remote versions (where speakers are connected) and hardware:
- pulseaudio-0.9.13-6.fc10.x86_64 (intel8x0 audio)
- pulseaudio-0.9.10 (Ubuntu 9.10 version, i386, emuk10k1 and intel8x0 on ICH4)
- pulseaudio=0.9.13-0.2-1 (Foresight Linux 2.1 version, i386, intel8x0 on nforce2)

Remote network connection: 54MBps wifi, 100Mbps and 1GBps ethernet. Connection speed doesn't change symptoms in any way.

How reproducible:
Always

Steps to Reproduce:
1. Use paprefs to turn on zeroconf sink announce and discovery.
2. Start music playing in Totem
3. Use pavucontrol to move Totem stream to remote speakers.
  
Actual results:
Choppy sound and local PA crash. Remote PA daemon doesn't crash!

Expected results:
Smooth playback.

Additional info:
Ubuntu 9.10 i386 live plays to remote Ubuntu 9.10 over wifi without any problem. Bandwidth utilisation is about 110KB/s. Yet Ubuntu has old PA version (0.9.10).

The tunnel module in PA upstream has been reworked to be a bit more robust.
