Status: RESOLVED WORKSFORME

(addons.mozilla.org Graveyard :: Add-on Builder, defect)

Description

[Wes Kocher (:KWierso) (Not reading bugmail; email directly if needed)]

I was using Builder.addons.mozilla.org earlier tonight to try to help someone figure out how to do something. After test-installing an extension and then making a change to it (thus, reinstalling it), I noticed the following message logged in the Error Console:
error: An exception occurred.
Traceback (most recent call last):
  File "resource://jid0-2flkb0o1uja6xf5yrte13azedpc-at-jetpack-api-utils-lib/utils/registry.js", line 55, in _destructor
    for each (instance in _registry)
ReferenceError: assignment to undeclared variable instance

I'm using the latest mozilla-central nightly build, in a new profile, with addon builder helper v0.0.19, on the release version of the Builder website.

Steps to reproduce:
Create an add-on on Builder.
Save and test that add-on.
Make a change to the add-on's code and save it (triggering a reinstall).
See the message in the error console's "messages" tab.

Beta's fine, too...

So is Aurora.

Okay, I give up. Now I'm getting the error message on a mozilla-central build from last week. I was using Nightly all last week working in Builder, and I WASN'T seeing this message back then...

We're going to need steps to reproduce or this is WFM.
