Christoph Haas has kindly provided a Cream 0.36 package in Debian "experimental" which I'm using with the Vim 7 beta package in the same place.  Now, all of my icons are broken (i.e. they show as "broken icon" icons with a red X -- my workaround is to right-click on the toolbar and select "Text only").

This doesn't happen with gvim 7 without Cream, so I'm wondering what it is that Cream does differently that I should be looking for.  Any clues?
