Well, it wouldn't be the first time. (One only learns by being
wrong occasionally...) But, in this case I'm pretty sure
of myself. ;-)

Here is your problem. g_slist_alloc() does not allocate
a singly-linked-list, it allocates one node of a singly
linked note. [ And one very seldom has to call that function
directly, since nodes are usually allocated by g_slist_prepend()
or g_slist_append() ]

As in my example last time, the correct way to allocate
an empty GSlist is.

 GSList *Llist;
 llist = NULL;

Yep, a empty GSList is just a NULL pointer. (There are no
nodes, so nothing to point to.)

Hope this clears things up,
