Comment (by adamsilverstein):

 This is still reproducible and was also reported to me by another user.

 It can easily happen when you:
 * import posts into WordPress (for example the test data @iseulde
 mentioned) and then
 * trigger an autosave  by making a small edit and waiting until the
 autosave triggers, then
 * Reload the post and click the link to "View the Autosave".

 Because the post is imported, the expected "initial" post revision is
 missing. Revisions takes care of this, but a bug meant the "author" it
 tried to use did not exist. We can just use the revision author here
 instead.

 [attachment:"31249.diff"] fixes the issue.


 Before this fix, I also saw a JavaScript error viewing these autosaves,
 after the fix the screen worked as expected.
