The "reprojection" of the vectors using ogr2ogr is badly breaking them, so
when I burn them using gdal_rasterize I get spurious lines ove

Hey Andrew,
Are your files in the same projection? I know gshhs is projected in wgs84
by default, and I see your raster is in British National Grid. AFAIK,
gdal_rasterize assumes the vector & raster data sets are in the same
projection.

Hi Markus,
A friend of mine just tried this out on r15709 and reports that it works
fine. Are you referring to the syntax in the original email not working, or
what I advised Andrew to try? If it's the latter, please send the command
you're using, so we can dissect it.
Thanks,
Roger

Andrew,
I believe your syntax is incorrect. Assuming that you are trying to exclude
water from your image, it should be something like this:
% gdal_rasterize -b 1 -b 2 -b 3 -i -burn 0 -burn 0 -burn 0 -l gshhs_land
