The icon files in the contained 64x64, 48x48, 32x32, 24x24, and 16x16
pixel images with 8-bit and 32-bit depths.  I've checked in a change
removing the 32-bit versions, leaving only 8-bit ones.  Can anyone who's
having problems see if this helps?

BTW, does anyone know of a good way to convert the 256x256 PNG icons in
the repository to a Windows icon that conforms with the guidelines in
http://msdn2.microsoft.com/en-us/library/ms997636.aspx?  I'm using
IconLab, but it apparently creates icons that some programs don't like.
