I encountered this while configuring my tracker (using
a metakit backend) to integrate with svn.

Here's the exception from the logfile:
2005-07-21 10:43:07,974 ERROR top level
Traceback (most recent call last):
  File "/home2/svn/RD/hooks/notify-roundup.py", line

"/usr/local/lib/python2.3/site-packages/roundup/backends/back_metakit.py",
line 311, \
in close
    self.indexer.close()

The straightforward solution is to replace the
offending function call (line 311 of back_metakit.py) with:
        if hasattr(self.indexer,'close'):
          self.indexer.close()

Even better, I've implemented the close() method on all indexers.
