Problem with editors w/o authors

Hi again,

Another problem. I'm getting errors when bibtexing entrys that have no 
"author" fields -- this is what bibtex yields :
You can't pop an empty literal stack for entry dtc
while executing---line 2884 of file jurabib.bst (twice for each entry)

It often happens that this type of error do not have any consequences 
when latexing the file, though. But when author's fields are empty, I 
get the following message :
  Argument of \jb@doitem has an extra }.
<inserted text>
                 \par
l.18   {{Richelieu}{}{}{}{}}
                              {} \bibAnnoteFile {richelieu95}
?
Runaway argument?
! Paragraph ended before \jb@doitem was complete.
<to be read again>
                    \par
l.18   {{Richelieu}{}{}{}{}}
                              {} \bibAnnoteFile {richelieu95}
?
! Argument of \jb@doitem has an extra }.

This leads to undefined citations.

Can somebody help?  Below is the really-minimal-example.
Thanks,
Hélène Fernandez.
