Yep, that should be the cause!

This issue does not make any sense to me.
Not only am I unable to reproduce this, the error seems completely unrelated too.

The error would suggest that this is caused by a broken addons item. I added some additional logging, so try on the latest build again and post the new error. Then we will know what addon caused this error message.

Thank you very much
