tablePositions empty assertion error in version 1.0

[Thomas Morrison <Th...@microfocus.com>]

The attached fo document causes the tablePositions assertion, requesting
that the fo be sent.

The full output of the rendering is:

processEvent
WARNING: Font "Symbol,normal,700" not found. Substituting with
"Symbol,normal,400".

SEVERE: tablePositions empty. Please send your FO file to
fop-users@xmlgraphics.apache.org

The table-header is rendered at the end of the table.

The PDF is renedered the same on 0.95, although the output is different,
not mentioning the two WARNINGs:

org.apache.fop.layoutmgr.table.TableContentLayoutManager addAreas
SEVERE: tablePositions empty. Please send your FO file to
fop-users@xmlgraphics.apache.org

The table-header is rendered correctly in 0.20.5 with the following
output:
[INFO] Using org.apache.xerces.parsers.SAXParser as SAX2 Parser
[INFO] FOP 0.20.5
[INFO] Using org.apache.xerces.parsers.SAXParser as SAX2 Parser
[INFO] building formatting object tree
[INFO] setting up fonts
[INFO] [1]
[WARNING] Sum of fixed column widths 500000 greater than maximum
specified IPD 0
[INFO] [2]
[INFO] Parsing of document complete, stopping renderer

I have searched for a possible cause, and would like a workaround if not
a fix.  I have so far been unable to determine what aspect of the table
header may be triggering this behavior.
