Nautilus self-check
 

I have a problem with starting up Gnome and on some forum they taught that it might be a Nautilus problem.
So I tried
nautilus -c (the Nautilus self-check)
Here is what appeared:

running nautilus_self_check_search_uri
running nautilus_self_check_file_utilities
running nautilus_self_check_file_operations
running nautilus_self_check_directory

FAIL: check failed in nautilus-directory.c, line 1729
evaluated: g_hash_table_size (directories)
expected: 1
got: 2

And then it holds - probably not responding, so I end it up with CTRL-C.
What's the problem?
Thanks
