This message appears because you are using chroot.
You have to edit /var/unbound/unbound.conf and add a trailing slash to
value of the 'directory' parameter:

server:
    ...
    chroot: /var/unbound
    directory: /var/unbound/
    ...

When unbound uses chroot, it determines the directory name, that it will
be use for chdir call, taking in account the value of 'chroot'
parameter. If 'chroot' equals 'directory' the unbound will call
chdir(''), which will cause an error.
