Segfaults with dialogs

(Bug report from Julien.)

I'm running on Arch64.

I have encountered some segmentation faults which crashed the game. Here is what I got with gdb :

(gdb) run Starting program: /usr/bin/solarus [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/libthread_db.so.1".

It happened only during dialogs but it randomly appears (at the beginning, or inside the cave... only when there is dialogs)
