[Wine] Open With "A Wine Application": a ridiculous amount of trash

[xxxxme]

How do I remove all the "A Wine Application" entries (http://img32.imageshack.us/img32/1413/winetrash.png) from gnome's Open With > Add Application dialog?

As well, for almost every file type I had when wine started doing this, there's an entry in gnome's right-click menu (http://img215.imageshack.us/img215/4291/winejunk.png) to open with "A Wine Application".  Often, this is the default.  I've gotten most of these removed now, doing one at a time when I noticed them.  How do I stop this ridiculousness when I use wine on another account?
