This line was in my watchlist:

Clicking the (diff) link sent me to https://en.wikipedia.org/w/index.php?title=Wikipedia_talk:WikiProject_Breakfast&workflow=ropnaopuy0b5yp2w&topic_oldRevision=rrpzj5dmf5xpum28&topic_newRevision=rrpzij853a0phqfi&action=compare-post-revisions
which shows me this:

PHP fatal error in /usr/local/apache/common-local/php-1.23wmf19/extensions/Flow/includes/Templating.php line 452:

(Note: I know the moderation/deletion system is in the process of being reevaluated, so this bug is likely to be cleared up by that work. I'll add more details on expected behaviour (when a non-admin tries to view deleted content) another day.)
