Bibtopic/jurabib incompatibility (w/ @archival entry)

Hello,

I've encountered a strange behavior of jurabib while trying to use 
\fullcite inside a text.  The presence of the bibtopic package forces 
lines to overlap... when bibtopic is not present, everything turns out 
to be OK. Guess this is a side-effect of using \baselineskip.

cheers,
Hélène Fernandez.

Here is the example :
\documentclass[a4paper]{book}
     \usepackage{jurabib}
     \usepackage{bibtopic}

\begin{document}

     \bibliographystyle{jurabib}

     \emph{« Discours du président du parlement de Dijon sur le sujet du
     procès criminel de ceux qui ont suivi Monsieur~» : \fullcite[f.
     103-105]{md811}}.

     \begin{btSect}{SourcesMs}
        \section{Sources manuscrites}
        \btPrintCited
     \end{btSect}

\end{document}

SourcesMs.bib contains :
@archival{md811,
    archive         = {Archives du ministère des Affaires étrangères},
    shortarchive    = {A.E.},
    subarchive      = {Mémoires et documents, France},
    shortsubarchive = {M.D. France},
    sig1            = {811},
}
