With the following versions of ConTeXt, LuaTeX, and t-bib:

MTXrun | main context file: /opt/context/beta/tex/texmf-context/tex/context/base/context.tex
MTXrun | current version: 2009.04.21 16:11
This is LuaTeX, Version beta-0.40.0-2009042222 luatex.web >= v2344
%D \module
%D   [       file=t-bib,
%D        version=2009.04.17,

Using the following in a file named bibliography.bib:

@TechReport{WhoAmI2009,
author =       {Who Am I},
title =        {Foo, Bar, Baz},
institution = {Boo},
year =         {2009},
number =       {42},
month =        {January}
}

With the following as my test file:

\usemodule[bib]
\usemodule[bibltx]
\setupbibtex[database=./bibliography]
\setuppublications[sorttype=bbl,criterium=all]
\setuppublications[numbering=short,autohang=yes,refcommand=key]

\starttext
\input knuth \cite[WhoAmI2009]
\stoptext

I get the following error:

! Undefined control sequence.
<argument> ... [\bibrefprefix ][\sectionseparator
                                                  ]

                                                  \storeitem
\gotobiblink ...brefprefix \preparebibreflist {#2}

If I change \cite[WhoAmI2009] to \cite[short][WhoAmI2009], then the document will build without errors if there are no intermediate files but without actually inserting the citation key: I just get the empty pair []. If there are intermediate files, then I get the familiar:

! Undefined control sequence.
<argument> ... [\bibrefprefix ][\sectionseparator
                                                  ]

                                                  }\@@expanded
\preparebibreflist ...refix ][\sectionseparator ]}
                                                  \storeitem

l.8 \input knuth \cite[short][WhoAmI2009]

I hope this helps!

1. The problem with the bib module persists. I don't get any errors anymore about undefined control sequences, the bbl file is loaded, but no output is produced. I hope I can produce a minimal test file tomorrow, unless you already have a test.

a test file would be handy indeed as i have no clue how to invoke the bug
