Title:
  Destroying pkgCacheFile releases system lock

Status in apt package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: python-apt

  This code should work, but doesn't:

   >>> import apt_pkg
   >>> apt_pkg.init()
   >>> with apt_pkg.SystemLock():
   ...     x = apt_pkg.Cache()
   ...     del x
   Reading package lists... Done
   Building dependency tree
   Reading state information... Done
   Traceback (most recent call last):
     File "<stdin>", line 3, in <module>
   SystemError: E:Not locked

  (lines beginning with ... should be indented, but Launchpad collapses
  multiple spaces into one when not at the beginning of the line)

  Architecture: amd64
  apt 0.8.10ubuntu1
  python-apt 0.7.100.1ubuntu4
