Hi Jukka and everyone
This seems to have worked (with a tweak to your rasterizer command):
gdal_rasterize -burn 100 -l mask mask.shp image.tif
I've recreated the layer, and I still seem to get broken graphics when I preview it via embedded GWC. I've put the two blanked-out tiles here:

If you or anyone wants to experiment with them, and see if you also run into problems, please do. Let me know if you want any further details of my set-up to try to recreate the same conditions.
Thanks again
Tom

Hi,
I have not tried myself, but it might be doable with gdal_rasterize
http://gdal.org/gdal_rasterize.html
Digitize a big polygon that covers your images, save as "mask.shp" and then
run
gdal_rasterize -burn 100 -l mask.shp image.tif
Not sure if it works with paletted images but try and you will see.
