If a new directory tree is created within guitone, the first 
creation of a new node within a new node (f.e. rename target or 
added node) causes inconsistent repeated workspace updates (see 
first attachement and note the 500ms time span in between, 
apparently the InventoryWatcher timer behaves wrongly!) or even 
segfaults (second attachment).
