I may have found a similar problem.

I run rsnapshot on a dedicated hammer filesystem, mounted nohistory.
Recently, I have discovered some directories couldn't be properly rotated:

# du -sh *
du: weekly.0/anego.zefyris.com/usr/local/share/icons/hicolor/128x128/stock/text:
No such file or directory
  0B    weekly.0
du: weekly.2/anego.zefyris.com/home/ftigeot/Maildir/.Dragonfly-kernel/cur: No such file or directory

# ls -la stock 
ls: text: No such file or directory
total 0
drwxr-xr-x  1 root  wheel     0B Apr  2 04:03 .
drwxr-xr-x  1 root  wheel     0B Apr  2 04:03 ..

# rmdir stock 
rmdir: stock: Directory not empty

# rm -r stock 
rm: stock/text: No such file or directory
rm: stock: Directory not empty

Some directory entries are not visible with the normal tools, yet seem to
exist someway.

The machine crashed violently recently (power failure); the hammer filesystem
was re-mounted without any apparent error.
