Can't import qbzr?

[Eli Zaretskii]

I only now noticed that every time I type "bzr help hidden-commands",
there's an error message in .bzr.log complaining about qbzr.  Here's
an example:

  Sat 2011-05-28 20:20:39 +0300
  0.110  bazaar version: 2.3.3
  0.110  bzr arguments: [u'help', u'hidden-commands']

  0.157  looking for plugins in D:/usr/Bazaar/plugins
  0.438  encoding stdout as sys.stdout encoding 'cp1252'
  0.922  Can't import qbzr or some qbzr functions, not defining GUI commands.
  ImportError: No module named qbzr
  1.344  Transferred: 0kB (0.0kB/s r:0kB w:0kB)
  1.344  return code 0

I don't have qbzr installed, so why does it look for it?

I had these messages since v2.3.1 at least, according to the log.
