** Description changed:

- Test case:
- - generate a cachedb with apt-ftparchive from lucid via
-    apt-ftparchive --db old-db 2vcard_0.5-3_all.deb
+ TEST CASE:
+ 1. generate a cachedb with apt-ftparchive from lucid via
+    apt-ftparchive --db old-db packages 2vcard_0.5-3_all.deb > Packages.1
  - use apt-ftparchive from precise and run
-    apt-ftparchive --db old-db 2vcard_0.5-3_all.deb
-   and verify that the hashsums are no longer correct
+    apt-ftparchive --db old-db 2vcard_0.5-3_all.deb

- The archive.ubuntu.com master server has just been upgraded from lucid to precise.  As a result, the apt version went from 0.7.25.3 to 0.8.16~exp12, and apparently some time in that interval the on-disk format of apt-ftparchive's cache changed.

  This wouldn't be a problem, except apt-ftparchive itself doesn't
  *notice* that the cache format has changed, and instead happily reads
  the existing files and parses them incorrectly, resulting in corrupted
  checksums output in the Packages file for each of the .debs.
  
  apt-ftparchive should version its file formats so that it correctly
  notices incompatible cache files.
