Yes, I did that.  That's what I meant by "I do not use defadvice in this way in
my code anywhere (anymore) - I use only `ad-get-arg'."  By "anywhere" I meant in
_any_ of my code.

None of my code (or other 3rd-party code that I load) uses defadvice with a
named argument.  It uses only `ad-get-arg' when it accesses arguments.

And the Icicles code, which is the code invoking the call to
`documentation-property' that raises the error, has only two defadvices, neither
of which accesses any argument.

So it seems to me that this bug is unrelated to #8457.
But I could be wrong, of course.
