When I click in one of my (Echo) notifications on mw.org it shows this:
[3b4db816] 2014-08-22 02:00:04: Fatal exception of type MWException
Any idea what that could be?
Also, the red icon for new notifications doesn't change to gray until I open Special:Notifications
Maybe it is related to Flow, since the notification in question is about someone creating a new topic.
