You can't tell from the backtrace, but I think I know what this is. Wine sometimes does FBO blits directly to the front buffer. This currently tends to crash due to the front buffer surface not being created yet. The attached patch should help with the crash, but it may not be enough to make the actual blit work correctly.

Your guess was right, the patch from attachment 44652 fixes the bug. Tropico works perfectly now with hardware 3D acceleration enabled (though it's a little bit slow).
