Are you, by any chance, creating this image by locking focus on an NSImage and then drawing? NSCachedImageRep is more or less obsolete in Snow Leopard, but before SL, if you did this, you ended up with an NSCachedImageRep instead of an NSBitmapImageRep. In any case, one way of working around this problem is by putting the NSCachedImageRep into an NSImage if it isn't in one already, calling -TIFFRepresentation on the image, and using the resulting data to create a new NSBitmapImageRep.
