NewUserMessage tried to edit my user talk page, but not properly through Flow. So I got a notification, but no actual message:
This particularly affects gomwiki/Konkani because Flow is enabled everywhere there, so user talk is Flow even without a Beta Feature being turned on (a user turning on the Beta Feature would turn it on after NewUserMessage was done).
It could affect other wikis, though (e.g. it would affect MediaWiki.org if NewUserMessage was enabled).

This is from Extension:NewUserMessage, which does not handle Flow. We should take this as an opportunity to finally fix T123522: Implement a server-side mw.MessagePoster equivalent.
We should also see if we can defend against other extensions doing this wrong (maybe fail instead of creating a blank page)

Mentioned in SAL (#wikimedia-operations) [2016-09-14T23:34:40Z] <dereckson@tin> Synchronized wmf-config/InitialiseSettings.php: Add logging channel for NewUserMessage (T131957) (duration: 00m 47s)
I didn't realize this was actually creating corrupt pages (I thought they were just blank), so we need to disable it. It's not doing anything useful anyway, but there is a chain of fixes for this (almost merged) that will allow us to do it properly.
Change 330601 had a related patch set uploaded (by Mattflaschen):
Disable NewUserMessage gomwiki to prevent corruptions
Change 330601 merged by jenkins-bot:
Disable NewUserMessage gomwiki to prevent corruptions
It would have been more appropriate to disable Flow, since NewUserMessage is an established extension.
