"Remote I/O error (121)" trying to delete a remote directory containg files.

[gv]

Description of the problem:
Most of the times I cannot delete directories that have files or others directories on a remote machine (I connect using cd ​sh://user@host/home/user). I get something like this:

Cannot remove directory "/sh://user@h~home/user/1
                 Remote I/O error (121)
      [ Skip ]  [ Skip all ]  [ Retry ]  [ Abort ]

For most of directories in /home/user it does not work. Occasionally, for some directories, it works. And I cannot find a pattern here.

The only workaround for this issue is to first manually remove files from the directory and then remove the directory itself. This is easy if the directory tree is small. But for sure not feasible for a large directory tree.

Steps to reproduce:

1. ssh user@host
2. mkdir 1
3. copy some random files into directory 1
4. connect from mc to the remote host using ​sh://user@host/home/user
5. try to remove directory 1 by pressing F8 on the directory.
