Still seen on 1.33-wmf.3, with a slightly different stack trace. For example:

Thanks for the update! Please keep us informed. We have some ideas what is causing this (e.g. the page got deleted the moment the user submitted the conflicting edit) and will fix it, but it's a bit down in our queue and will take a while.
