http://bugs.debian.org/395203
* Non-maintainer upload.
* In test_osutils.py, sort what we get from os.listdir() before checking it;
  the OS can give back directory entries in whatever order it likes, and
  this shouldn't break the tests. Fixes intermittent test failures and
  FTBFS. (Closes: #395203)
