An analysis of what happened was circulated a few days ago and now published: https://wikitech.wikimedia.org/view/TranslationNotifications_issues_2012-12 It's fairly technical but it's supposed to help improve for the future, although so far it wasn't acted upon: «TL;DR: Changes in MW core exposed a bug in TranslationNotifications. The same bug is also present in other extensions. Many people participated in preventing further damage and fixing the issue. More work remains to be done.»
Since that report is not on a generally editable wiki, let me note here instead that while it gives the impression that the first duplicate notifications were observed at the end of November, this has in fact happened at least twice before, in July and August:
https://meta.wikimedia.org/wiki/Talk:Translation_requests#Double_notificatio...
Examples: https://meta.wikimedia.org/w/index.php?diff=3964877&oldid=3964809 , https://meta.wikimedia.org/w/index.php?diff=4049992&oldid=4049949
Back then, the time between the redundant notifications was much shorter, so the reason may have been a different one.
We still don't know if the translation notifications should now work or what's going to happen to the job queue, nor how/if todays' jobqueue disaster (http://article.gmane.org/gmane.science.linguistics.wikipedia.technical/65703 ) may impact it.
Thanks to everyone who worked to resolve the present bug! I have a small notification (Portuguese only) to send out soon, which should make a good test case.
