I think the problem is this line:
	list = gtk_tree_store_new(1, G_TYPE_STRING);

later:

Tool *tool
...
gtk_tree_store_set(list, &row, 0, tool, -1);

You should probably be using G_TYPE_POINTER instead of G_TYPE_STRING.

See:
http://en.wikibooks.org/wiki/GTK%2B_By_Example/Tree_View/Tree_Models

"G_TYPE_STRING - stores a string in the store (makes a copy of the 
original string)
G_TYPE_POINTER - stores a pointer value (does not copy any data into the 
store, just stores the pointer value!)"

Well, I didn't study your code for long, but:
Tool *tool = g_slice_new(Tool);

Somehow you need to g_slice_free(Tool, tool) for each call to 
g_slice_new. Maybe by iterating the tree store when you've finished 
using it.
