Unfortunately the CIMI client is now pretty broken because we're =
implementing
more CIMI entities and making the CIMI frontend compatible with v1.0.

So if you apply this patch, then you will get another error... I think =

now working on fixing this, so hopefully we will have proper patch for =
the client
soon.
