Re-opening a resolved Flow topic, adds links to the history that give fatal errors. (2 types, might need to be split into 2 tasks)
E.g. (please don't edit this topic) the top "cur" link at http://en.wikipedia.beta.wmflabs.org/w/index.php?title=Topic:Spcn7a9iurr9va0b&action=history
leads to http://en.wikipedia.beta.wmflabs.org/w/index.php?title=Topic:Spcn7a9iurr9va0b&action=compare-postsummary-revisions&topicsummary_newRevision=spcn8wt86omraot4&topicsummary_oldRevision=spcn9enyj02pjkew
which says:
An error has occurred.

Possibly related, or might need to be split-out...
Changing the title, at a topic that is otherwise identical, e.g. http://en.wikipedia.beta.wmflabs.org/w/index.php?title=Topic:Spcmomfi73pwaauj&action=history
leads to a different error at http://en.wikipedia.beta.wmflabs.org/w/index.php?title=Topic:Spcmomfi73pwaauj&action=compare-post-revisions&topic_newRevision=spcmu8q6vsnxng9k&topic_oldRevision=spcn37uj8w0gfxwr
