[viewvc-dev] sometimes query db goes wacky

Sometimes, I stop being able to query about a certain repository
beyond a certain date in the past.  I get this:
An Exception Has Occurred
Python Traceback

Traceback (most recent call last):
  File "/opt/viewvc-1.0.4/lib/viewvc.py", line 3665, in main
    request.run_viewvc()
  File "/opt/viewvc-1.0.4/lib/viewvc.py", line 388, in run_viewvc
    self.view_func(self)
  File "/opt/viewvc-1.0.4/lib/viewvc.py", line 3482, in view_query
    commits.append(build_commit(request, files, limited_files, dir_strip))
  File "/opt/viewvc-1.0.4/lib/viewvc.py", line 3308, in build_commit
    file=request.server.escape(f.GetFile()),
  File "/opt/viewvc-1.0.4/lib/sapi.py", line 165, in escape
    return cgi.escape(s, quote)
  File "/usr/lib/python2.2/cgi.py", line 1024, in escape
    s = s.replace("&", "&") # Must be done first!
AttributeError: 'NoneType' object has no attribute 'replace'

Not sure how or why it happens, but if I wipe the info on the
repository out of the query db and then reload it, things are happy
again.  Any hints?
