Hi all, 

I was trying the following bib example on MkIV beta 2009.11.20 and luatex beta-0.44.0-2009103007.
There isn't an apparent error message, but neither the bib reference or the publication list appears in the pdf.

Observations: 
1. In MkII, it works well.
2. In MkIV, if you use the [criterium=all] option, both bib ref and pub list show properly. Other criterium, e.g. [criterium=section] doesn't work.

thanks a lot.

regards,
shenchen
