"stop" hook fails

[Andreas Hasenack]

Hi,

the "stop" hook of the juju-gui charm fails:

2013/04/22 14:28:03 INFO worker/uniter: running "stop" hook
2013/04/22 14:28:04 INFO worker/uniter: HOOK Traceback (most recent call last):
2013/04/22 14:28:04 INFO worker/uniter: HOOK File "/var/lib/juju/agents/unit-juju-gui-0/charm/hooks/stop", line 6, in <module>
2013/04/22 14:28:04 INFO worker/uniter: HOOK from utils import (
2013/04/22 14:28:04 INFO worker/uniter: HOOK ImportError: cannot import name stop
2013/04/22 14:28:04 ERROR worker/uniter: hook failed: exit status 1

I suppose this does not happen with pyjuju because the stop hook is not called, but it does happen when deploying the charm and destroying the service using gojuju. After having called "juju destroy-service juju-gui", I got this in status and the above small backtrace in the unit logs:
