Title:
  UnicodeDecodeError loading config file containing invalid UTF-8

Status in Bazaar Version Control System:
  In Progress
Status in “bzr” package in Ubuntu:
  Triaged

Bug description:
  Binary package hint: bzr

  10.10 amd64
  bzr 2.2.1-0ubuntu1

  I see similar bugs, but I'm not sure if this is exactly the same.
  This is on a branch which has only been lightly touched, and I haven't
  knowingly created any files, let alone ones with unusual filenames.  I
  ran bzr commands, such as status, yesterday with no problems, but
  today, running bzr status:

  ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

  bzr: ERROR: exceptions.UnicodeDecodeError: 'utf8' codec can't decode
  byte 0xa6 in position 4097: invalid start byte
