Bug Description

AlertEngine from NAV 3.5.0b2, patched with the changeset references by Thomas Adamcik in https://bugs.launchpad.net/nav/+bug/293624, still crashes with UnboundLocalErrors on some installations.

This time the log looks like this:

Changeset http://metanav.uninett.no/hg/default/rev/ee9e92afb08a not being applied is most likely the culprit in this case. I've asked Morten to verify this fix on the box in question.

I've patched the code, and it's running fine now. AFAIK the bug occurs only when dispatching queued alerts, so it might not show up immediately if it is still there.

Since this has been in default a while now, and no new errors have been posted I'm closing this one now.
