I reproduced the error with virtual machines from virtualboxes.org. So it's easy to set up the same testing environment to reproduce the error for everybody who wants to.
In both cases I used the same mp3 file, the same zen vision:m and the same host (btw. it's the same machine as above) 1. I took the 11.10 virtual box image from virtualboxes.org as is. (no update, just sudo apt-get install gnomad2). gnomad2 transferred the music track perfectly. 2. I took the 12.04 virtual box image from virtualboxes.org as is. (no update, just sudo apt-get install gnomad2). gnomad2 failed the same way as above. - console output: Device 0 (VID=041e and PID=413e) is a Creative ZEN Vision:M.
