[CF-Devel] Server crash: more info

[crossfire-devel-admin at archives.real-time.com]

Experimented on my local server.
There's a bug with dragon abilities, and i think that's why 
crossfire.metaforge.net crashes.

Playing a fire dragon (default attenuation). When i become level 15 i 
get dragonbreath, but that crashes the server.
Explanation, from player.c:3073
    item = &(tr->item->clone);
 
    /* grant direct spell */
    if (item->type == SPELLBOOK) {
    if (check_spell_known (who, item->inv->name))
        return;

with tr->item->name == "spelldirect_dragonbreath"
except item->inv is NULL
so breaks at item->inv->name

That explains why only I would crash cf.mf.net, since i'm (for now) the 
only fire dragon, and i'm REALLY close to getting level 15... So killing 
something gets me over the edge, and crashes with null pointer...

Now I don't know enough about the new skill system to fix that...
