* apt-pkg/acquire-item.cc:

  - remove 'old' InRelease file if we can't get a new one before
    proceeding with Release.gpg to avoid the false impression of a still
    trusted repository by a (still present) old InRelease file.
    Thanks to Simon Ruderich for reporting this issue! (CVE-2012-0214)
