HTTP 417/422 prevents sync with Tracks

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Install Shuffle. enter some actions. 
2. Enter Tracks server URL, login, password. Verify.
3. Synchronize

What is the expected output? What do you see instead?
Expected: Data should appear same in both locations.
Instead: No evidence of synchornization

Log output shows that we receive a 417 error, which accounts for the problem.

What version of the product are you using? On what operating system?
Shuffle: 1.7.0b3
Android 2.2.2, HTC MyTouch 3G w/Jack

Please provide any additional information below.

The HTTP 417 looks like this. In this case I was attempting to sync with 
"tracks.tra.in"

Hello

I also have a problem of this kind (I cannot sync to tracks.tra.in, neither 
with shuffle, nor with another android app).
My question is : how to provide informations ?
I've installed adb and associated drivers for debugging my mobile, but when I 
test synchronizing capability of shuffle, I see very few debug traces about 
Shuffle.

What do I miss ?
Is there a way to enable/disable specific Shuffle trace ?

My platform is : android 2.3.4 on Xperia mini pro

I also suspect no sync is happening i;m using version 2.0.2 and can see no 
evidence once so ever that its even trying to sync, check my firewall logs 
nothing..

Any clue as to what my be or not be happening, the only reason to use this app 
is for its syncing ability with tracks standard install.

I've stopped using android-shuffle, mainly because of this problem
