Hi Tassilo,

You might be right that it is in my code (dunno), but if so I don't think it has
to do with the problem you mention.  The problem you mention is, I think, bug
#8457 (which has reportedly been fixed, BTW).

I do not use defadvice in this way in my code anywhere (anymore) - I use only
`ad-get-arg'.  And in the Icicles code I use defadvice in only two minor places,
neither of which accesses an argument (by name or otherwise).
