I have found out what is causing the above error. Every time you try to
make a clone where the target for the clone is a different storage than
the storage of the source the error above is thrown.

Following use cases have been tried with the same result:
source      target    result
nexenta     zfs       fails
nexenta     local     fails
nexenta     nexenta   success
zfs         nexenta   fails
zfs         local     fails
zfs         zfs       success

seems that command 'exec' in IPC/Open3.pm cannot be executed on a
tainted command which normally is seen when path is not untainted.
