[NTG-context] Bib module and prefix=+

[Robin Kirkham]

Hi,

How can the bib module and \setuphead[chapter][prefix=+] be made to  
coexist?  The following example works, but if you uncomment the  
\setuphead, the citations are broken and the reference list vanishes:

\setupoutput[pdftex]

% uncomment this line and it breaks
%\setuphead[chapter][prefix=+]

\usemodule[bib]
\usemodule[bibltx]
\setupbibtex[database={xampl.bib}]
\setuppublications[refcommand=num]

% makes no real difference
%\setuppublicationlist[title=\chapter]

\version[temporary]

\starttext

\chapter[chapt]{A Chapter}

Some citations: \cite[article-full] \cite[inbook-full] \cite[manual- 
full].
This is chapter~\in[chapt].

\completepublications[criterium=all]

\stoptext


Any help much appreciated!

PS: The following old mailing list article appears to describe the  
same problem, but the symptoms are different (citations disappear,  
but reference list does not)
