I downloaded build 1.0.4.0217_beta from Google Play and it crashed immediately after installation. I then Uninstalled and re-installed with exactly the same results. I then Uninstalled and downloaded the apk file from the MM website. When installed it gave exactly the same failure. As soon as you try to use the application it dies... badly. I then uninstalled again and installed the 1.0.4.0214_beta build and it works fine.
I also installed the 1.0.4.0217_beta on an Asus Memo 10 and it works fine on that machine so I guess the problem is machine specific. I did send the logs of the system failures. The Xoom is my main music machine for use when I am cooking so losing MM on that specific machine is a definite pain....

If there is any more information that might help please let me know...
