Admins and oversighters cannot view revdeleted or suppressed content when the diff is of a Wikibase item, and the edit content is hidden.

Viewing the diff with &unhide=1 from the logs generates an error "This data set does not exist. You can search the related logs to find out where it went. You can also create a new one. " when it is viewed, even if the item exists.

Viewing the revision from the page history results in the following error:

The database did not find the text of a page that it should have found, named "Q3234584" (revision#: 72322553).

This is usually caused by following an outdated diff or history link to a page that has been deleted.

If this is not the case, you may have found a bug in the software. Please report this to an administrator, making note of the URL.

Content can be viewed through Special:RevisionDelete, however.

There are no problems when the edit content is left visible, and the summary or username are hidden.
