Clicking the "History" tab at two Flow-enabled pages at Enwiki, currently results in this error message:
[426b142b] 2014-09-08 21:13:32: Fatal exception of type MWException

Additionally, the Wikiproject Breakfast page itself, is showing that error:
Topic-History is still accessible at /Developer_test_page.
The other 3 pages at Enwiki, and the other 2 wikis on wmf19, all appear to be fine.
