Further testing shows that the failure to compile issue (#1 and #2 
above) is tied to processing @ARTICLE bib entries. The failure occurs in 
and out of footnotes and startquotation blocks. I really was too deep 
into a wrong view of the problem to see that before. That is pretty 
clearly a bug.

The issue with method=font and left, right, middle (#3, #4, #5 above) is 
still problematic. This is not tied to the bibliography system.
