My Trac (multirepos-r8782) instance uses AccountManagerPlugin and requires login to view the contents. By chance I've discovered that if I click on the "About Trac" link without logging in then everything is fine, but after logging in it produces an internal error shown below. Obviously it is somehow related to the AccountManagerPlugin plugin and how (badly :) I've configured it, but IMHO Trac should not fail so disgracefully on the about page and the code where the exception happens looks suspicious - the dictionary components is filled up from one source ComponentMeta._components, but then items are extracted from it by keys that are taken from another source - Option.registry.items(). Probably these sources should be in sync but they are not in this case. IMHO the proper fix would somehow combine these two sources into one and eliminate such an errors all together but the following simple patch plugged it for me

How to Reproduce

While doing a GET operation on /about, Trac issued an internal error.

comment:4 by Remy Blank, 15 years ago

This is due to AccountManagerPlugin defining that particular option ([account-manager] account_changes_notify_addresses) in a class that is not a Component. When I wrote that code, I assumed this was a requirement, but this is not the case.

Resolution: fixed
Status: newclosed

Fixed in [8804]. As we have no way of knowing if an Option defined in a non-Component class is enabled or not, it will always be shown. Of course, it would be better if AccountManagerPlugin defined that Option in e.g. AccountChangeListener, so that it can be hidden if the component is disabled.

Thanks for the bug report!
