+SDL2 UI sends a NULL to sdl_grab_start if fullscreen, which crashes
+
+in ui/sdl2.c:
+
+    if (full_screen) {
+        gui_fullscreen = 1;
+        sdl_grab_start(0);
+    }
+
+Is sent, but no null checks are made in sdl_grab_start (its assumed to be an allocated pointer). So a crash happens if you start qemu -full-screen.
+
+It should at lease send the first [0] of the newly allocated sdl2_console through.
+
+Quickly looking around should look something like:
+
+    if (full_screen) {
+        gui_fullscreen = 1;
+        sdl_grab_start(&sdl2_console[0]);
+    }
+
+The NULL pointer check has been added here:
