When saving as "OpenRaster archiving image" there is no thumbnail saved inside the archive. Quoting the spec (http://create.freedesktop.org/wiki/OpenRaster/File_Layout_Specification): "Thumbnails/thumbnail.png This file is highly reccommended, in order to get previews in file browsers. It should contain the final (possibly cropped) image without any frame or decoration. It must be a non-interlaced PNG with 8bits per channel of at most 256x256 pixels. It should be as big as possible without upscaling or changing the aspect ratio. This file must not be referenced in any .xml file."
Upgrade from wish to bug.
