Same Bug 637160 ?

Yes, this does appear to be the same issue, although I do not believe this is tied to any content policy extensions as they suggested in the other bug. If this needs to be marked as a Dup, that works with me, I just couldn't find any related bugs in my earlier searches.

Bulk move to Toolkit::Notifications and Alerts Filter on notifications-and-alerts-component.

Seems this got fixed in bug 637160.
