Hey, I just found the problem:
abiword is allocating a tree path with gtk_tree_path_new(), but freeing it with g_free (vs. gtk_tree_path_free). As gtk_tree_path_new does not necessarily use malloc() but may also utilize faster memory management functions, this leads to the described free() error. Besides, using g_free() will leak memory. A patch is attached. This fixes the problem for me, which I have been able to reproduce on amd64. Kind regards, Patrik
