Still seeing this error.

We traced this to a bug that happens when there is a deleted page on your watchlist. I have a hunch on which extension is causing the problem. We'll follow up as soon as we catch the culprit.

It looks like this is a bug in the Echo extension. We have a patch waiting for review. Can you please check if this is fixed?

[lwaldron]

Yes looks fixed.
