[Wine] Using a custom library in iTunes

[501st_alpha1]

I have installed iTunes in Wine! Yay!

However, I have a slight problem. In order for iTunes to be any use to me, I need to access my music library, which is stored on my data partition. Usually, one holds the shift key while opening iTunes, and it gives the option to choose library or create a new one. However, in my Wine install of iTunes, this doesn't work, it just opens it to the default library anyway. (I would move my library, but I would like to be able to still access it from my Windows install, just in case. Plus I like to keep my data separate.) Are there any workarounds to this, or should I file a bug report?

Wine 1.2.2
iTunes 10.1

Need any other info?
