Unfortunately that hasn't fixed it.  I managed to get a core file loaded 
into GDB so I can give you some more information.  Execution eventually 
ends up in getContractionTableCharacter which tries to call 
getContractionTableHeader which fails because its an external table.  
Some of the traceback is below, do you have any ideas?
