wine users - May 2011 - iTunes doesn't work after upgrading to Ubuntu 11.04

I recently upgraded to Ubuntu 11.04, and iTunes has stopped working. It worked
fine in 10.10; I had been using it with Wine 1.2.2. I tried it in 11 with Wine
1.2.2 and 1.3.14, both unsuccessfully. I will try 1.3.19 later tonight.

With both versions of Wine, it opens and appears to work, but my music
doesn't show up. I still see my playlists though, so I think it can see the
library. I tried using the same wine prefix as in Ubuntu 10 for Wine 1.2.2, and
I made a fresh one for Wine 1.3.14, both with the same result.

Here is the Pastebin (http://pastebin.com/0Wa9wTsJ) for the developmental
version. The first block of code is running winecfg, and the second block is
installing iTunes.

Any ideas?

P.S. I am using the classic GNOME desktop, not Unity.
