Advanced chown: wrong set files permissions

[zack24]

The old problem, exists since 4.6
When setting files permissions on a group of files
often the permission of upper dirs getting changed.
Many times the permissions change of the / (root) dir has been observed.

To reproduce the bug do:

1. Find * (all files in the dir)
2. Select them all - dirs and files.
3. Menu > File > Advanced chown
4. change read write execute flags
5. Apply.

Check the permission of the root dir
like this:

1. mkdir /tmp/root
2. mount -B / /tmp/root
3. cd /tmp
4. ls -lF

[pavlinux]

1. mkdir /tmp/root
2. mount -B / /tmp/root
3. cd /tmp
4. ls -lF

drwxr-xr-x 23 root root 4096 Янв 12 11:38 root/

# ls -lF /tmp/root/
