hi, actual openttd's ebuild installs different sized icons in /usr/share/pixmaps/openttd.{size}.png, and the menu entry point at the 64x64 ones (openttd.64.png); with this patch ebuild installs these icons in the right path in /usr/share/icons/hicolor/{size}x{size}/apps/openttd.png and menu entry points to te right icon; this enhancement provides a freedesktop standardized installation ;) i hope you'll use this patch best regards
