---------------------

The code base is that of 2004-07-16 around 9.00 MEZ (head).

Commenting out the offending line 191 in RtfListTable caused the conversion to
run through, though resulting in not conformant rtf.

The same file converted OK with a fop version that was approximately three
months old (also head).

The fo is produced using the current docbook stylesheets, originating from a
docbook source.
