My guess is you're using Zope 2.1.6.  ZDebug doesn't have a way to
figure out what DTML method is being called in Zope 2.1.6.  Strange but
true.  So it shows what it can.  The 2.2.x security context stack is
used to figure it out in 2.2.x.  (Which is still a hack. :-/ )

Oops!  Try this patch (I left out a "%s"):

Thank you.  I know when I was new to Zope this would have been
tremendously useful.  Now it's useful because it should help people
solve problems on their own rather than having to post to the list.
