Details:
I did found the following segfault in the sdl client while testing the mapimg
patches. This is a patched version of freeciv but the mapimg patches do only
touch color related parts of the sdl code. Thus, it should be reproducedable
on the trunk version.
How to reproduce: start the game and visit the nation dialog.
