config-get: "error: settings not found"

[Andreas Hasenack]

Hi,

I have this weird error in a config-changed hook. The charm calls
config-get --format json and it fails:

2014-03-17 09:42:42 INFO juju.worker.uniter uniter.go:348 running
"config-changed" hook
2014-03-17 09:42:42 INFO worker.uniter.jujuc server.go:108 running
hook tool "config-get" ["--format" "json"]
2014-03-17 09:42:42 INFO juju.worker.uniter context.go:255 HOOK error:
settings not found

Is there a normal scenario where this could happen, or is it a bug in juju?
