ofcourse, rename cant't be track if made out of nautilus but the problem  
is,
i renamed directory in nautilus window - so maybe it should update  
thumbnails of renamed directory.
problem would be if renamed directory has plenty of subdirectories, but  
caching only few levels inside
may solve this problem.

or maybe thumbnail shouldn't be assigned to file path, but only to a file  
- some hashkey made of file name
(without path), file size, creation time.


cheers, Mark
