Adding reedy:

Reedy, if this isn't fixed very quickly, we'll need to revert :/

Rob: Can you get that reviewed and merged and tested on beta cluster ASAP?

(grumble mid-air collision bz, really adding reedy now)

Asking here instead of in IRC:
What's the offending commit? When was it merged into master?

Verified the fix in test 2 and mw.org.VE is now loading properly on wmf10.

This is fixed on test2/mw.o but still broken on beta labs. Perhaps it was a hotfix in prod, but master not updated yet?

Synchronisation for betalabs has been broken for over a week due to bug 49846 – see http://en.wikipedia.beta.wmflabs.org/wiki/Special:Version which says "VisualEditor 0.1.0 (3e925e6) 20:50, 2 January 2014". Re-closing as that's a distinct issue.
