View is not smooth (but shaking left and right)

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Enable auto mode to use compass and accelerometer
2. Position the phone to point directly east (or west)
3. Slowly move the phone straightly up toward Zenith (you can also put it on a 
table in landscape mode when moving to make sure your hands are not shaking)

What is the expected output? What do you see instead?

I expect to see smooth upward moving of the map. Instead of that I am getting 
upward movement + some small left and right shaking. 
The issue is not present if I am doing the same thing while looking north or 
south.

What version of the product are you using? On what operating system?

I am using the latest version from the source repository, revision 7.

Please provide any additional information below.

The current location does not seem to matter, I tried to manually set 0 
latitude and 0 longitude and the issue is still present. 
The issue also reproduces if you are looking east (or west) an go down towards 
Nadir in a straight line. But is OK with north and south.

Any idea were this shaking might come from?

I was able to reproduce this on a HTC Nexus One and a Samsung Galaxy S1.

Best regards,
Cristian
