--- Comment #18 from Michael Meeks <[email protected]> ---
Compression is based on a DPI calculation:

                                const double fSourceDPIX =
((double)aSourceSizePixel.Width / ((double)aLogicalSize.Width / 2540.0 ));
                                const double fSourceDPIY =
((double)aSourceSizePixel.Height/ ((double)aLogicalSize.Height/ 2540.0 ));

                                // check, if the bitmap DPI exceeds the maximum
DPI
                                if( ( fSourceDPIX >
rGraphicSettings.mnImageResolution ) || ( fSourceDPIY >
rGraphicSettings.mnImageResolution ) )

Might be good to run through the sdext/source/minimizer/impoptimizer.cxx
(ImpCompressGraphic) method in a debugger for this image and see what is going
on.

Potentially there might be some horror mapmode problem causing grief. I need to
re-build with the extension enabled to do more it seems.
