Comment 5 for bug 940948

I have a new installation of Ubuntu 12.04 with Google Chromium, and I have recorded for you a video in real time to show you that for me the Ubuntu One Web Music player is really unusable. In the video you can see in the up right corner the time with the seconds, no trimming, no cutting.
As you can see, I need three attempts to access the tab Music because the "504 Gateway error", and when eventually I'm in, and I choose an artist, I have another error with the message "An error has occured. Our engineers have been notified and we will work to fix this".
note: I have reported this problem in February 2012, and since then nothing is changed.
