Follow-up Comment #1, bug #16865 (project freeciv):

Probably "pPlayer0->string16" should be "pPlayer0->info_label".

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.

I could produce another one using trunk (svn16977)
