In recent gtk versions gdk-pixbuf is now split out again (after being
merged in 2002). Using that would be a good solution. The intermediate
solution would be to make the make it rdepend on the current pixbug package.

Now, the *real* solution would be to check if an icon cache is actually
needed before trying to run gtk-update-icon-cache. ISRT the cache format
is an FDO spec, but I'm not sure.
