CatalogAware doesnt' work very well, don't rely on it :-S

Your code could use refactoring ;-)
The problem was that propdict returns the property metadata, not the value of 
the property. You want getProperty for that...

      def __init__(self, default_catalog='mycatalog'):
        self.default_catalog = str(default_catalog).strip()
        self.keywords = self.get_indexablekeyword()
        self.fulltext = self.get_indexablefulltext()

      def get_indexablekeyword():
          " Dynamically build indexable attributes "
          propdict = PropertyManager.propdict(self)
          keylist = []
          for name,entry in propdict.items():
              thisType = entry['type']
              if thisType == 'string':
                  keylist.append(self.getProperty(name))
              elif thisType == 'boolean':
                  keylist.append(name)
          return keylist

      def get_indexablefulltext():
          " Dynamically build indexable attributes "
          alltext = ''
          for name,entry in propdict.items():
              if entry['type'] == 'text':
                   alltext += self.getProperty[name]
          return alltext

cheers,
