How do I get rid of a corrupted filename ( / inside ) in ext4 home mount point?

/home sudo ls -l rubish
ls: can't access rubish/tongue/gif: none file of folder of that kind
total 0
-????????? ? ? ? ?              ? tongue/gif

I could move the folder to the top of /home but I can't move it outside another partition:

sudo mv rubish /svr
mv: unable to evaluate "rubish/tongue/gif": none file of folder of that kind

Thank you
